How many search engines




















Search engine history all started in with Archie, an FTP site hosting an index of downloadable directory listings. Search engines continued to be primitive directory listings, until search engines developed to crawling and indexing websites, eventually creating algorithms to optimize relevancy. Yahoo started off as just a list of favorite websites, eventually growing large enough to become a searchable index directory.

They actually had their search services outsourced until , when they started to really work on their search engine. Google's unique and improving algorithm has made it one of the most popular search engines of all time. Other search engines continue to have a difficult time matching the relevancy algorithm Google has created by examining a number of factors such as social media, inbound links , fresh content, etc. As evidenced by the above infographic, Google appeared on the search engine scene in Google was unique because it ranked pages according to citation notation, in which a mention of one site on a different website became a vote in that site's favor.

Google also began judging sites by authority. A website's authority, or trustworthiness, was determined by how many other websites were linking to it, and how reliable those outside linking sites were. Google search history can be witnessed by taking a look at Google's homepage progressions over the years.

It's remarkable to see how basic and primitive the now most popular search engine once was. A picture of the original Google search engine homepage, back when Google was part of stanford. While Google is widely regarded as the most popular search engine, there are also a number of alternative search engines one can use. Different search engines exist for unique needs.

For example, you may want a search engine to help you search for blogs specifically, or perhaps you want search engines for kids that only return sites appropriate for children. These free search engines enable you to easily find information that caters to your unique needs. In addition to standard search engines, there are deep web search engines as well. The deep web refers to areas of the internet that are not susceptible to normal indexing, and so can't easily be found and indexed by crawlers.

These alternative search engines specialize in this not-easy-to-find data. Below is our top 10 internet search engines list. While deciding which is the "best" search engine depends on your unique wants and needs, below is a list of popular search engines, some more unique than others.

This is the fastest form of search. Archie The first search engine - it searched FTP sites to create index of downloadable files Due to limited space, only the listings were available and not for the contents for each site. Veronica Searched file names and titles stored in Gopher index systems. Jughead Also searched file names and titles in Gopher index systems, but only searched a single server at a time.

Bot was soon upgraded to capture actual URLs Database was called Wandex Bot accessed same page hundreds of times a day and caused lag. Infoseek Webmasters could submit a page in realtime. Iam coming goiing. I've always liked Bing, a perfectly relevant search engine without the social controversy generated by Google. Thank you sir give me a important information. Thank you sir for give me important information. Such an informative post. Thanks for sharing. Very nice Good Lol????????????????????????

You missed engines built on a business model like Cuil. Ha ha like China and Russia we indian also will make one search engine and operating system I am telling you all Americans bye bye.

The application model that orders the search engine results according to categories. Boris Pevzner mtpl. It is known that the quality of a search according to key words is significantly affected by the algorithms of ordering output websites. As rule, an user takes account opens links only the sites located on first page of output search result. Those systems that use categorization allow the user to navigate the possible choices more accurately.

But modern search engines have no categories. The main function of the application is to assign category codes to output sites Flws.

The algorithm is based on the principles of learning machine and data mining. Our application is autonomous independent object. It is connected with Google or other search engine through two standard points-enter key words and output results-links The developers of the application will not work with Google codes.

It should note, that the categories are not search parameters and they are used to make easier the selection of the required Web site. Creating learning set of each category. We selected some generic categories computer, medicine, agriculture, technology, linguistics, science, education and so on. By means of google searches we got the set of websites of each category two first pages- 40 websites. It is the file corresponding to one of category.

Flunit is transformed into a category vector Vcat, It is the learning set of the category. Algorithm of categorization The algorithm is based on the principles of learning machine and data mining. Main objects are the category vectors Vcat and the site vectors to which a code will be assigned Vws. Vcat consists of all different words of Flunit.

The dimension of Vcat is the number of different words of Flunit. It is the number of coordinates. Dimensionality of the coordinate is frequency of a word into Flunit. A website of output result Flws is transformed into a website vector Vws. Vws consists of all different words of Flunit Vcat. The dimension of Vcat is equal the dimension of Vws.

Our software calculates cosine of an angle? Cosine between two angles is calculated in this way , where xi,yi,zi are vector coordinates. We have the following sequence of pairs for each category Vcat. The software orders these pairs for reducing cos?. If cos? For checking of cosine as a proximity measure we made a small test. We had Vcat. We selected the Website website1 of first page and the Website of second website2. Our program created two vectors Vwb1 and Vwb2.

Nevertheless, there are other search engines worth considering, and the best Google alternatives are presented below. No need for further introductions. Google holds first place in search with a stunning difference of According to statistics from statista and statcounter , Google is dominating the market in all countries on any device desktop, mobile, and tablet.

What made Google the most popular and trusted search engine is the quality of its search results. Google is using sophisticated algorithms to present the most accurate results to the users. Over the years the Google ranking algorithm has been enriched with hundreds of other factors including the help of machine learning and still remains the most reliable way to find exactly what you are looking for on the Internet. The best alternative search engine to Google is Microsoft Bing. Their search engine market share is constantly low even though Bing is the default search engine on Windows PCs.

From October to October , Yahoo search was powered exclusively by Bing. In October Yahoo agreed with Google to provide search-related services and until October , the results of Yahoo were powered both by Google and Bing.

Baidu has a global market share between 0. Baidu was founded in and it is the most popular search engine in China. Its market share is increasing steadily and according to Wikipedia , Baidu is serving billions of search queries per month. It is currently ranked at position 4, in the Alexa Rankings. According to Alexa , Yandex.

Yandex presents itself as a technology company that builds intelligent products and services powered by machine learning. According to DuckDuckGo traffic stats , they are serving on average 47 million searches per day but still their overall market share is constantly below 0.

Unlike what most people believe, DuckDuckGo does not have a search index of their own like Google and Bing but they generate their search results using a variety of sources. This is a big limitation compared to Google that has a set of algorithms to determine the best results from all the websites available on the Internet.

On the positive side, DuckDuck Go has a clean interface, it does not track users and it is not fully loaded with ads.
