The three major search engines:
-MSN (Bing) by Microsoft
are all in competition with each other. Their goal is to provide searchers with the best possible results - determined by their individual search algorithms.
There are also other META search engines like Dogpile, Lycos or ASK which compile data usually from the major ones.
Searchers choose to use the search engine they believe provides them with the best results. Google is by far the most popular followed by Yahoo, then Bing.
By using multiple search engines you can get more results and information. However, sorting through all the results can also be confusing and time consuming.
That would be known as a meta search engine.

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.
There are two types of search engines 1. Hybrid search engines 2. Meta search engines
