To understand what a Meta Search Engine, First you need to understand how search engine works. There are billions of websites present on internet so search engine creates databases of various websites is called as index. Example suppose there are literature, entertainment websites on internet then search engine will create 2 databases, one is for literature and other is for entertainment. Now when user put some keyword to search on internet then search engine will find out relevant page according to the keyword which user has enter. So now back to how search engine works. Meta search engines don’t have a repository or index of their own, they take advantage of indices created by other search engines. A typical Meta search pulls off the results from a number of search engines say Google, Bing etc and then apply their own algorithms to re-order the results.
Are Meta Search Engines Better?
Let me explain with an example: Now suppose you are looking something that is on website ‘Z’ and using Google search engine but after you hit the query you don’t get any result of website ‘Z’. Now it might be possible that website ‘Z’ is present on other search engine i.e. take Yahoo but you are using Google right?? Now in this case Meta Search will work. If you hit same query in Meta Search Engine then it might give results so in this case Meta Search Engine will be helpful because it pulls the results from different Search Engines.
