What is a meta search engine?

In Wikipedia, I found this definition:

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.

The importance of Meta Descriptions Tags has changed over time. Initially it was felt that they helped a web page rank highly for the keywords within the tag, but there's general agreement in the SEO world today that this is no longer the case.

Meta search is one of the tool of every search engines, it shows your some more search engines database so that you can chose the best one which you are looking for, that is it.

Meta search engines enable users to enter search criteria once and access several search engines simultaneously. Meta search 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.

Meta description is an important part in SEO and there is some limitation also in meta description also.

A meta search engine searches multiple search engines from a single search page.
Meta search engines work in various ways. With some, a single, simultaneous search retrieves results from multiple sources, usually with the duplicates removed. Others offer a separate search of multiple content sources, allowing you to select the source(s) you want for each search.
When a single simultanous search is offered, only a limited maximum muber of pages from each source are returned. The cut-off may be determined by the number of pages retrieved, or by the amount of time the meta engine spends at the other sites. Results retrieved by these engines can be highly relevant, since they are usually grabbing the first items from the relevancy-ranked list of results returned by the individual search engines. Keep in mind that complex searches, such as field searches, are usually not available.

Metasearch engines create what is known as a virtual database.

Meta search engines are search engine tools that pass queries on to many other search engines and then summarize all the results

Metasearch means instead of getting results from one search engine, you'll be getting the best combined results from a variety of engines

Meta search engine is a search engine which is retrieve relevant information from other search engines.

A search engine that queries other search engines and then combines the results that are received from all. In effect, the user is not using just one search engine but a combination of many search engines at once to optimize Web searching.

A meta search engine submits your query to several other search engines and returns a summary of the results,Who use its own algorithm to choose the best results from multiple search engines.

Meta search engine that ranks results based on the number of "top 10" rankings a site receives from the various search engines.

Sorry, I don't what is it! But from this conversation I little knows about this topic.

Search engine is a most important part of the searching.In effect, the user is not using just one search engine but a combination of many search engines at once to optimize Web searching. For example, Dogpile is a metasearch engine.

How do they arrange the links? Is it depended on the search engine's popularity?
