A search engine is a database of specific information on the Internet. Many users believe that as soon as they enter a query into a search engine, they immediately start scanning the entire Internet, but this is not at all the case. The Internet is scanned constantly, by many programs, data about sites are entered into a database, where, according to certain criteria, all sites and all their pages are distributed into various kinds of lists and databases. That is, it is a kind of data filing cabinet, and the search does not take place on the Internet, but according to this filing cabinet.

The search engine does not work, the developers suggest using the search engine.

Most of the time a user spends on the Internet is spent looking for information of interest to him. At the same time, there are many ways to get this data - you can look into the online encyclopedia and try to find the answer there, you can subscribe to a mailing list on a topic of interest and carefully study the incoming correspondence, or you can consult with competent people on the forum by asking them a question. But the most universal way to find something on the Internet is to use one of the many search engines. Services for searching millions and millions of websites are, perhaps, the fundamental link of the worldwide web. Without Google, Yahoo, Yandex and many other search engines familiar today, a user's stay on the Internet would be more like a blind man walking in the woods. The importance of search engines for working on the Internet can hardly be overestimated - many users have start pages the addresses of search engines are indicated, and it is from them that an endless journey through various network resources begins for many. However, the effectiveness of Internet excavations is different for everyone - one person finds information instantly, another takes a lot of time, and the third may not find anything useful at all. What is the reason? The answer is simple: searching on the Internet is akin to fishing - you need to know where to fish and what to fish with, i.e. where to look and how to look. In today's article, we will talk about how best to conduct a search on the Internet, and tell you what search engines exist for this, except for those that are "on everyone's lips."

However, we will start with exactly those systems that you know. If a user knows the address of a search engine, this does not mean that he knows how to use it. Let's check how well you understand search query technology. How accurate the results you get depends primarily on how skillfully you have formed your search query. For example, if you are looking for information to write term paper, you do not need to enter its topic verbatim, especially if the work has a narrow specialization. You will find much more valuable information if you try to find keywords, that is, those words that will definitely appear in your work. If you are looking for a lost manual for a car radio, then by entering the model number, you will surely get a huge number of sites offering to purchase it. To filter out unnecessary links, you can use the search function or exclude some words from the search. In almost every search engine, you will find an advanced search function. This is another good way weed out unnecessary results. Among these functions, it can be useful to search for pages that have recently been updated, search for pages only in a specific language, or on sites located in the domain zone you specify. The time spent on searching can be significantly saved if you know and use the syntax of the query language. Each search engine has its own characteristics here. For example, when you are looking for something on Yandex, it will not be superfluous to use the following techniques:

To search for words that should appear on the page in the same sentence, put the & symbol between them
To exclude a specific word from search results, add it to your query by preceding it with ~~
To find pages that contain at least one of the words specified in your search query, separate them with |
To search for a word in the specified form, put an exclamation mark in front of it

The Google search engine also has its own secrets. Here are just a few of them:

To search for information on a specific site (and only on it), enter its address in the request field, preceded by the word site and a colon (for example, site: http: //www.site)
To search for a phrase that must appear on the page in full, put it in quotes
To exclude pages containing a certain word from search results, add it to your query by placing a minus sign in front of it

These are just a few of the touches that can help make your web search more effective. If you want to achieve the best result, we advise you to familiarize yourself in more detail with the syntax of the query language, which is described in detail in the help system of your favorite search engine. There is no doubt that Google and Yandex are indispensable tools for searching the web - search in these systems is convenient, flexible and very accurate. But, nevertheless, this does not mean that alternative search engines have no right to exist. Yes - they index fewer pages, yes - their resource selection methods are largely controversial. But such search engines have one undeniable advantage - they offer something new, different from the accepted standards. Since alternative search services use a different approach to the selection of resources that match the query, the search result will be completely different than in the case of conventional search engines. So, if a long search on well-known services did not lead to anything, this means one thing - you need to change your tactics and try other methods of finding information using alternative search engines. Often, alternative search engines use one or more listings of resources to collect results that have been found by Google, Yahoo and other major systems. These results are filtered, the best ones are selected and often visualized for better perception using a chart, sitemap, tag cloud, etc. Developers of alternative search engines sometimes go so far in their search for a new universal interface that it is sometimes difficult to recognize a search engine in a web page. And yet, these are search engines. Unusual and strange, at first glance ...

FindSounds.com - searches for sounds

This resource is intended for those users who are in a creative search. The resource allows you to search for audio files of different formats - wav, mp3, aiff, au. The resource database contains a wide variety of sounds - animal screams, rattling of cars, ringing, knocking, sirens, buzzing insects, roaring explosions and gunfire, splashing water, etc. Sound files can be searched for by different criteria, for example, by size, presence of two or one sound channels (stereo / mono), sampling frequency and sound depth. In the search results, the resource shows not only links to the files found, but also their main characteristics, and also shows a graph of the sound amplitude, by which one can judge the nature of the sound of a given sample.

Base sound effects FindSounds can be used in a wide variety of areas - from the development of computer games and other applications to the creation of presentations and all kinds of clips. The search engine can be useful, for example, for those who create interactive web graphics and want to add variety to the site by accompanying the clicking of the page navigation elements with various sounds.

Gnod.net - will select music, books and films to taste

When a person has a desire to read a new book, listen to some new music or watch a movie, he usually turns to his friend or acquaintance for advice, who has authority in his eyes. However, it is not so easy to find someone who would agree to express their opinion on this issue. Firstly, not everyone likes to give advice, because recommending something to someone else, a person takes on a share of responsibility, and many are stopped by the question "What if the film I recommend doesn't like him?" Secondly, the person who gives advice must understand what the interlocutor will like and what will be completely uninteresting. After all, the taste and color, as they say ... But there is an easier way to get good advice - to use a special search engine, which is made for this very purpose. So, you wanted to listen to a new band, but there is no time or desire to look for good music. The gnod.net resource will ask you a few names of music artists that you like, analyze the results and suggest your own version of a singer or band that you should also like. The service has several databases - on music performers, on films, books and people. Thus, the resource has incorporated four services: Gnod Music, Gnod Books, Gnod Movies, and Flork. The latest service, Flork, is a social experiment to discover people who are interested in interacting with each other. We were happy to test the music section of this service and brought in three artists - Gerry and the Pacemakers, The Beatles and Hollies. Our selection was not accidental - these three groups belong to the era of the sixties, to an interesting phenomenon called the British Invasion. All of these bands played the beat, and the search engine had to suggest a band or artist in the same style. And so it happened. The result offered to us is the Archies, which in the late sixties was on the lips of all Americans with their merry song Sugar Sugar. After playing with the search engine for some time, we came to the conclusion that gnod.net often gives the right advice, but does not make mistakes very often. For clarity, the search engine can provide the results of its "advice" in the form of an animated cloud with the names of groups, authors or films. The database can be replenished independently, conducting "conversations" with the search engine and answering his questions in the style of "I like this" or "I do not like this".

Alldll.net - will find library files

We recommend that you bookmark this search engine right away, as sooner or later it will definitely come in handy. Probably, everyone has at least once encountered the problem of the absence of some dll library in the system. Usually this leads to the fact that programs or games refuse to start, and the message "Couldn" t find *****. Dll "appears on the screen. There can be many reasons for this, for example, the absence of a file may be caused by an incorrect deletion earlier installed application, accidental file damage, etc. In addition, the developer could simply not include this library in the distribution of his product.

It is very simple to fix the situation - just find the missing file on the Internet, download it and copy it to the directory of the program that refuses to start, or to the folder..WINDOWSsystem32 ... You can quickly and easily find and download the missing file using this service. The www.alldll.net resource is a searchable database of the most popular dll libraries. Files are sorted alphabetically, there is a search function. You can search for the file you are looking for even if you only know the approximate name of the library. It is enough to start entering text in the request field, and a huge list of files will appear at the bottom of the page, which begin with the letters that have been typed.

Medpoisk.ru - search for medical information

Although this search engine uses Google's search engine, this in no way diminishes its value. Medpoisk.ru is a universal search engine designed to search exclusively on medical websites. This site is a great tool for every physician and anyone who wants to get an answer to any question in the field of medicine. How to treat this or that disease, what are the contraindications for this or that medicine, which doctor to go to - all this and much more can be learned by "asking" a search engine. The search engine includes a labor exchange and can be used to find work among medical professionals. The resource also contains a catalog of medical institutions sorted by region. Among these institutions are the addresses of clinics, medical centers of different directions, maternity hospitals, diagnostic centers, beauty salons, etc. We sincerely wish you to use this search service solely out of curiosity, and not out of necessity.

Taggalaxy.de - search for pictures and photos

You may have heard of the popular image sharing service Flickr.com? This is the same service that was blocked by the Chinese authorities in 2007 after pictures of the sad events of 1989 in Tiananmen Square, located in the Chinese capital Beijing, appeared on its pages. Flickr.com was one of the first Web 2.0 services with billions of images uploaded by users. The number of images uploaded to the servers of this service is so great that in order to find a specific image in this ocean of images and pictures, a separate search engine is needed. The service offers an image search service, but there is a more interesting way to search for images - using the unusual search engine taggalaxy.de. This search service is a search engine for images on Flickr.com, with a preview. What makes it extraordinary is the search interface, which is completely three-dimensional. The process of searching for a keyword resembles some kind of computer game - different celestial bodies fly in outer space, between which you can move in the virtual world.

After the query for the keyword is fulfilled, a system of the sun and planets that revolve around the star will appear on the screen. Each celestial body has its own purpose and is "signed" by the word. In the center of the galaxy is the sun, the key query, all other bodies are auxiliary words, clarifications. If you click on the sun, this object will come closer, and from all sides, photographs will flock to it and surround them, the content of which is determined by the search query. This three-dimensional model with photographs can be rotated in virtual space, examining in detail and looking for the image of interest. After that, it is enough to click on the picture to enlarge it, and then it will be possible to better examine it and read the description.

In the process of working with this search engine, you can use the scrolling function - it allows you to zoom in or out of three-dimensional planets. The rest of the planets that are visible in the search engine interface after the request are auxiliary words that allow you to refine the request. For example, if you enter "Sky" in the search field, then among the qualifying words-planets there will be the words "clouds", "sunset", "blue" and other tags that are similar in meaning that users indicated when using the Flickr.com service. The disadvantage of the search engine is that taggalaxy.de does not support Russian, so queries can only be entered in Latin.

Nigma.ru - filters the results of other search engines

Among all the search engines that can be found on the Internet, there is a special group of search engines. It differs from all the others in that they have a multi-search function, that is, a simultaneous search in several search engines. One of such multi-search systems is the Russian service Nigma.ru.

Nigma contains its own resource base, but in addition, it allows you to search all the most popular search engines at once, including Google, MSN, Yandex, Rambler, AltaVista, Yahoo and Aport. The selection mechanism for this search engine is different from most accepted site discovery methods. The point is that the engine of this service uses clustering of results. What does this mean? Imagine that you have decided for yourself to find out what "rendering" is. Comparing the results in different search engines, the Nigma.ru engine selected the most likely results, and at the same time, in the left part of the window, next to the list of search results, it displayed the so-called clusters - "visualization", "creation", "system", "rendering", "process", "studio max", " computer graphics"and other words and phrases. These clusters represent a thematic group of found documents. Thus, you can quickly narrow your search or narrow your search query. In Nigma.ru, you can also use headings to limit the area from which results will be selected - for example, search only based on musical resources or display results only for images. Another possibility of this service may be of interest to schoolchildren and students. Nigma.ru offers services Nigma-mathematics and Nigma-chemistry. The first is designed for quick solution of simple equations and various arithmetic operations , the second allows you to work with the formulas of chemical reactions.The search service recognizes more than a thousand physical, mathematical constants and units of measurement, allowing you to quickly perform the conversion from one dimension to another.

Searchme.com - search engine with preview

Everyone knows that it takes a lot of time to find specific information on the web. When browsing search results, the user basically opens resources at random, not knowing for sure whether he will find on new page what interests him, or it will be a waste of time. The creators of the searchme.com search service thought about this problem and came up with an original solution. The essence of this solution was to create a search engine in which the user could look at a rough thumbnail of the page before it loads. This would make it possible to form an additional opinion about the seriousness of the resource and about its content.

The implementation of this idea was just great - the created search engine has a beautiful animated three-dimensional interface and shows the search results in the form of an animated ribbon of thumbnails, thumbnails of screenshots of web pages that include the search keyword. The tape with the results, like the tape with the old negatives, can be scrolled in the browser window using the special slider located under the row of images. Sketches are instantly loaded, so there are no "brakes" with drawing the results. It is especially convenient to work with search results in full screen mode- then it is quite possible to make out even the text of the articles on the sketches of the results. To appreciate the convenience of this system, just try to browse the news resources. Photos for the main news on the title page of the web edition will immediately make it clear which news on this resource is considered the most important.

The way out is a specialized torrent search engine. There are a lot of sites that search for torrent resources on the network. However, torrent-finder.com has an undeniable advantage over other search engines - this service allows you to search for files on a huge number of trackers at the same time.

And Yandex is interested in users more and more. We will tell you about three non-banned search engines that do not collect personal information about you, but, on the contrary, protect your privacy.

Startpage: the world's most discrete search engine

Startpage.com calls itself "the world's most discrete search engine." Since 2016, the service has been merged with the Ixquick website. As proof of the security of its search, Startpage.com positions itself as the only search engine to have an EU privacy certificate.

Startpage.com promises not to store users' IP addresses and, according to the service, does not use cookies for tracking. In addition, Startpage.com is accessible from the Tor network. The search engine servers are located in the Netherlands. The site has a convenient feature: search results can be viewed using the "Proxy" option, which encrypts the connection to the corresponding web page using a proxy server. Thus, this is a real search engine without bans: you can safely browse what your provider is blocking. Search proxies are the main feature of Startpage, which makes it an uncensored search engine. If you need to search without blocking, this service is for you.

DuckDuckGo is the most widely used secure Google alternative with over ten million queries per day. Despite the fact that the search engine servers are located in the US, DuckDuckGo.com does offer some interesting features nonetheless.

When you search through DuckDuckGo.com, your IP address will not be saved. The system also does not use tracking cookies. DuckDuckGo uses HTTPS encryption. You can also enter a query into the search engine through the Tor network. In addition, you can use various themes to customize the display of the search page.

You cannot open sites through a proxy here. But given that the system is outside the jurisdiction of the Russian Federation, for example, the “right to be forgotten” in the sense in which it is understood in our country does not apply to it. The search results may not be perfect, but they are still quite useful. This service is more suitable for those who primarily value anonymity and search without tracking. Or those who want to find information excluded from search results in the Russian Federation. However, be warned: in Russia, DuckDuckGo has become a partner of Yandex, so you can expect everything.

notEvil: Search on the Internet that does not exist The notEvil search engine allows you to search from the Internet on the anonymous Tor network. To do this, you do not need to install any additional software(although you will need it in order to open search results).

This search engine allows you to search on the so-called darknet - that part of the Internet that is usually inaccessible to the average user. Due to blockages, they are gradually moving into it useful services, for example, to download content.

Anonymous search engines as a safe alternative to Google

All three search engines do not log your IP address and do not use tracking cookies. Encryption using HTTPS is provided by all named providers. The best search results in the test were shown by the search engine DuckDuckGo, and you will get guaranteed safety when choosing an alternative search engine with the Startpage.com system. The EU Data Protection Certification confirms that a search engine is sticking to its promises of search anonymity. For searching on the darknet, in turn, notEvil comes in handy.

Hello dear readers of the blog site. , then its few users had enough of their own bookmarks. However, as you remember, it happened exponentially, and very soon it became more difficult to navigate in all its diversity.

Then directories appeared (Yahu, Dmoz and others), in which their authors added and sorted various sites into categories. This immediately made life easier for the then, not yet very numerous users. global network... Many of these directories are still alive today.

But after a while, the size of their databases became so large that the developers first thought about creating a search within them, and then about creating an automated system for indexing all Internet content in order to make it available to everyone.

The main search engines of the Russian-speaking segment of the Internet

As you can imagine, this idea was realized with overwhelming success, but, however, everything turned out well only for a handful of selected companies that managed to survive on the Internet. Almost all search engines that appeared on the first wave have now either disappeared, or vegetated, or were bought by more successful competitors.

The search engine is a very complex and, importantly, a very resource-intensive mechanism (meaning not only material resources, but also human resources). Behind the seemingly simple, or its ascetic analogue from Google, there are thousands of employees, hundreds of thousands of servers and many billions of investments that are necessary for this colossus to continue to work and remain competitive.

Entering this market now and starting from scratch is more of a utopia than a real business project. For example, one of the richest corporations in the world, Microsoft, has been trying to gain a foothold in the search market for decades, and only now their search engine Bing is beginning to slowly meet their expectations. And before that there was a whole series of failures and failures.

What can we say about entering this market without much financial influence. For example, our domestic search engine Nigma has a lot of useful and innovative things in its arsenal, but their attendance is thousands of times inferior to the leaders of the Russian market. For example, take a look at Yandex's daily audience:

In this regard, we can assume that the list of the main (best and most successful) search engines of the Runet and the entire Internet has already been formed and the whole intrigue lies only in who will eat whom in the end, well, or how their percentage will be distributed if they all survive and stay afloat.

Search engine market in Russia it is very clearly visible and here, probably, two or three main players and a couple of minor ones can be distinguished. In general, a rather unique situation has developed in Runet, which, as I understand it, repeated itself only in two more countries in the world.

I'm talking about the fact that the search engine Google, having come to Russia in 2004, has not been able to seize the leadership so far. In fact, they tried to buy Yandex around this period, but something did not work out there, and now "our Russia" together with the Czech Republic and China are the places where the almighty Google, if not defeated, then at least met with serious resistance.

In fact, see the current state of affairs among the best search engines of the Russian Internet anyone can. It will be enough to insert this URL into the address bar of your browser:

Http://www.liveinternet.ru/stat/ru/searches.html?period=month;total=yes

The fact is that most of them use them on their sites, and this URL allows you to see the statistics of visitors from various search engines to all sites that belong to the RU domain zone.

After entering the given Url, you will see a picture that is not very attractive and presentable, but it reflects well the essence of the matter. Pay attention to the top five search engines from which sites in Russian receive traffic:

Yes, of course, not all resources with Russian-language content are located in this zone. There are also SU and RF, and common areas such as COM or NET are full of Internet projects focused on Runet, but nevertheless, the sample turns out to be quite representative.

This dependence can be formalized in a more colorful way, as, for example, someone on the network did for their presentation:

This does not change the essence. There are a couple of leaders and a few very, very lagging search engines. By the way, I have already written about many of them. Sometimes it can be quite entertaining to plunge into a success story or, conversely, delve into the reasons for the failures of once promising search engines.

So, in order of importance for Russia and Runet as a whole, I will list them and give them brief characteristics:

Search in Google has already become a household name for many inhabitants of the planet - you can read about that at the link. I liked the "translation of results" option in this search engine, when you received answers from all over the world, but in your native language, but now, unfortunately, it is not available (at least on google.ru).

The quality of their output (Search Engine Result Page) has also puzzled me lately. Personally, I always first use the runet mirror search engine (there is, well, I'm used to it) and only not finding an intelligible answer there, I turn to Google.

Usually their issuance made me happy, but lately it has only puzzled me - sometimes such nonsense climbs out. It is possible that their struggle to increase income with contextual advertising and constant reshuffling of SERPs in order to discredit SEO promotion can backfire. In any case, this search engine has a competitor in Runet, and what kind.

I think that hardly anyone will specifically go to Go.mail.ru to search on the Russian Internet. Therefore, the traffic on entertainment projects from this search engine can be significantly more than ten percent. The owners of such projects should pay attention to this system.

However, in addition to the pronounced leaders in the search engine market of the Russian-speaking segment of the Internet, there are several other players whose share is quite low, but nevertheless the very fact of their existence makes us say a few words about them.

Runet search engines from the second echelon

Internet-wide search engines

By and large, on the scale of the entire Internet, there is only one serious player - Google... This is the undisputed leader, but he still has some competition.

First, it's still the same Bing, which, for example, has a very good position in the American market, especially considering that its engine is also used on all Yahu services (almost a third of the entire US search market).

Well, and secondly, due to the huge share of users from China in the total number of Internet users, their main search engine, called Baidu wedges into the distribution of places on the world Olympus. It was born in 2000 and now accounts for about 80% of the entire national audience in China.

It is difficult to say anything more intelligible about Baidu, but on the Internet there are judgments that places in his Top are occupied not only by the sites most relevant to the query, but also by those who paid for it (directly to the search engine, and not to the Seo office). Of course, this applies primarily to commercial issuance.

In general, looking at the statistics, it becomes clear why Google there easily goes to the fact to worsen its search results in exchange for increased profits from contextual advertising. In fact, they are not afraid of the churn of users, because in most cases they have no special place to go. This situation is somewhat sad, but let's see what happens next.

By the way, in order to further complicate the life of optimizers, and maybe to maintain the peace of mind of the users of this search engine, Google has recently been using encryption when transferring requests from the user's browser to the search bar. Soon it will no longer be possible to see in the statistics of visitor counters for which requests users from Google came to you.

Of course, in addition to the search engines voiced in this publication, there are not one thousand others - regional, specialized, exotic, etc. It will not be possible to try to list and describe them all within the framework of one article, and, probably, it is not necessary. I'd rather say a few words about how difficult it is to create a search engine and how not easy and not cheap to keep it up to date.

The vast majority of systems operate on similar principles (read about and about) and pursue the same goal - to give users an answer to their question. Moreover, this answer should be relevant (corresponding to the question), exhaustive and, which is not unimportant, relevant (first freshness).

It is not so easy to solve this problem, especially considering that the search engine will need to analyze the content of billions of Internet pages on the fly, filter out unnecessary ones, and form a list (issue) from the rest, where the answers that are most suitable for the user's question will first go.

This extremely complex task is solved by preliminary collection of information from these pages using various indexing robots... They collect links from already visited pages and load information from them into the search engine database. There are bots that index text (regular and fast robots that live on news and frequently updated resources so that the latest data is always presented in the results).

In addition, there are image indexers robots (for their subsequent display in), favicons, site mirrors (for their subsequent comparison and possible gluing), bots that check the operability of Internet pages, which users or through tools for webmasters (here you can read about, and) ...

The indexing process itself and the subsequent process of updating the index bases is quite time consuming. Although Google does it much faster than competitors, in any case Yandex, which takes a week or two to do this (read about).

Usually, the search engine breaks down the text content of an Internet page into separate words, which leads to the basic basics, so that later you can give the correct answers to questions asked in different morphological forms. All the extra body kit in the form of Html tags, spaces, etc. things are deleted, and the remaining words are sorted alphabetically and their position in this document is indicated next to them.

Such shnyaga is called an inverse index and allows you to search not on web pages, but on structured data located on the servers of the search engine.

The number of such servers at Yandex (which mostly searches only for Russian-language sites and a bit for Ukrainian and Turkish) is in the tens or even hundreds of thousands, and for Google (which searches in hundreds of languages) - in the millions.

Many servers have copies, which serve both to increase the safety of documents and help to increase the speed of request processing (by balancing the load). Estimate the costs of maintaining this entire farm.

The user's request will be directed by the load balancer to the server segment that is currently least loaded. Then the analysis of the region from where the user of the search engine sent his request is carried out, and it is morphologically parsed. If a similar query was recently entered in the search bar, then data from the cache is slipped to the user so as not to overload the server.

If the request has not yet been cached, then it is passed to the area where the search engine's index base is located. In response, you will receive a list of all Internet pages that have at least some relation to the request. Not only direct occurrences are taken into account, but also other morphological forms, as well as, etc. things.

Their need to rank, and at this stage, the algorithm comes into play ( artificial intelligence). In fact, the user's request is multiplied by all possible options for its interpretation, and answers to many requests are simultaneously sought (due to the use of query language operators, some of which are available to ordinary users).

As a rule, the search results contain one page from each site (sometimes more). are now very complex and take into account many factors. In addition, to correct them, and are used, which manually evaluate the reference sites, which allows you to adjust the operation of the algorithm as a whole.

In general, it is clear that this is a dark matter. We can talk about this for a long time, but it is also understood that user satisfaction with the search engine is achieved, oh, how difficult it is. And there will always be those who do not like something, like, for example, you and me, dear readers.

Good luck to you! See you soon on the pages of the blog site
