That is not exactly true. A "meta search engine" pays importance only to the meta tags and meta discriptions of the HTML code. A search engine that searches many search engines is a mashed search engine, because it mashes the api of dfferent search engines. Examples for meta search engines are: http://metaspider.com/ or http://megaspider.com/ (very old) Examples for mashed search engines are: http://dogpile.com/ or http://avasearch.com/
Google is the biggest search engines.

The internet is a means of connecting computer resources it is NOT the biggest search engine. Search engines are IT applications attached TO the internet.
Submitting a site to the major search engines has to be done manually.
An example of non-meta-search engine is Google unlike Bing
Meta search engines combine results from different search engines. Some examples of this are mamma.com and dogpile.com.
You should use a metasearch engine if you need more results than you would from a regular search engine. You can also use certain metasearch engines like Ixquick or StartPage if you are concerned with privacy. Metasearch engines are usually not search engines themselves. They redirect traffic to actual search engines and then return the results. That can help privacy since the largest search engines record the details of your search. If you use a metasearch engine, then all the large search engines would have is that the metasearch engine performed a search on their sites using whatever terms at whatever time. If the metasearch engine doesn't record your search details, then it would be harder to trace the search back to you.
A meta-search engine is a search tool that sends user requests to several other search engines and/or databases and aggregates the results into a single list or displays them according to their source. Metasearch engines enable users to enter search criteria once and access several search engines simultaneously.
