Metasearch engine A metasearch 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. 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. The term "metasearch" is frequently used to classify a set of commercial search engines, see the list of Metasearch engine, but is also used to describe the paradigm of searching multiple data sources in real time. Operation architecture of a metasearch engine Search engines frequently have different ways they expect requests submitted. See also References
KartOO Meta-Search Engines-The Library "Smarter" meta-searcher technology includes clustering and linguistic analysis that attempts to show you themes within results, and some fancy textual analysis and display that can help you dig deeply into a set of results. However, neither of these technologies is any better than the quality of the search engine databases they obtain results from. Few meta-searchers allow you to delve into the largest, most useful search engine databases. Although we respect the potential of textual analysis and clustering technologies, we recommend directly searching individual search engines to get the most precise results, and using meta-searchers if you want to explore more broadly. The meta-search tools listed here are "use at your own risk."

Free Book Search Free Book Search's document search tool is designed to return the maximum number of online documents from specific types of websites as per the users' choice. We have made this search portal very robust so that using the tools on this page, if a document exists somewhere - even hidden away - on the Internet, you will find it here. This is one of the only online tools that will actually find books and documents on non-book sites. Most other tools sift through digital libraries or known locations of e-books and documents, our searches also scan private collections that are normally hidden. There are a few methods for finding documents, and we have tried to incorporate all of them in one place by using the 'radio buttons'. You may need to try using a few of the search techniques to find what you are looking for, and you may need to sift through a number of documents. We have included a military search to search official military sites.
