Search engines are necessary for locating, sorting, storing and ranking the value of that information on the web. Popular search engines like Google, Yahoo and Bing find relevant information and present it to users. In order to efficiently find a specific bit of data, it's important for you to know the four main functions of the search engines.
All engines for searching these days have their own websites. These engines by definition are online resources, and therefore, require a domain or website to function.
Sear Engines exist to organize and make all the information out there universally accessible and available to anyone. The Search engine main function is provides the high relevant web page when the user search with a particular key phrase.
There are two types of search engines 1. Hybrid search engines 2. Meta search engines
Spider-Based Search Engines. Directory-Based Search Engines. Link-Based Search Engines.
There are primarily three types of search engines: traditional search engines, vertical search engines, and meta-search engines. Traditional search engines like Google and Bing index the entire web and return results based on algorithms. Vertical search engines focus on specific niches or industries, such as medical or academic searches. Meta-search engines aggregate results from multiple search engines to provide a broader range of information.
Horizontal search engines are general-purpose search engines such as Google and Yahoo. Vertical search engines, meanwhile, are specialized by content such as Trulia, Mocavo and Yelp.

Generally speaking, meta search engines perform searches using a conglomeration of other search engines. Metasearch engines enable users to enter search criteria once and access several search engines simultaneously. Metasearch engines operate on the premise that the Web is too large for any one search engine to index it all and that more comprehensive search results can be obtained by combining the results from several search engines. This also may save the user from having to use multiple search engines separately.
