They use the indexes built by other search engines, aggregating and often post-processing results in unique ways. Advantages īy sending multiple queries to several other search engines this extends the coverage data of the topic and allows more information to be found. Another study later that year using 12,570 random user-defined queries from Google, Yahoo!, MSN Search, and Ask Jeeves found that only 1.1% of first page search results were the same across those search engines for a given query. Results found that from 10,316 random user-defined queries from Google, Yahoo!, and Ask Jeeves, only 3.2% of first page search results were the same across those search engines for a given query. In April 2005, Dogpile, then owned and operated by InfoSpace, Inc., collaborated with researchers from the University of Pittsburgh and Pennsylvania State University to measure the overlap and ranking differences of leading Web search engines in order to gauge the benefits of using a metasearch engine to search the web. The more stars in a result, the more search engines agreed on the result. It also uses a unique ranking system where a result is ranked by stars. Ixquick's privacy policy includes no recording of users' IP addresses, no identifying cookies, no collection of personal data, and no sharing of personal data with third parties. In June 2006, Ixquick began to delete private details of its users following the same process with Scroogle. Developed and launched in 1998 by David Bodnick, it is owned by Surfboard Holding BV. ![]() Ixquick is a search engine known for its privacy policy statement. It was developed by the then 16 year old Sumeet Lamba. In August 2000, India got its first meta search engine when was launched. This was later incorporated into another metasearch engine called Solosearch. Ī metasearch engine called Anvish was developed by Bo Shu and Subhash Kak in 1999 the search results were sorted using instantaneously trained neural networks. After going through a few alterations, HotBot was redesigned into a simplified search interface, with its features being incorporated into Lycos' website redesign. Upon being bought by Lycos in 1998, development for the search engine staggered and its market share fell drastically. It was known for its fast results and as a search engine with the ability to search within search results. On May 20, 1996, HotBot, then owned by Wired, was a search engine with search results coming from the Inktomi and Direct Hit databases. Metacrawler reduced the amount of search engines queried to 6, but although it produced more accurate results, it still wasn't considered as accurate as searching a query in an individual engine. This search engine improved on SearchSavvy's accuracy by adding its own search syntax behind the scenes, and matching the syntax to that of the search engines it was probing. University of Washington student Eric Selberg released a more "updated" version called MetaCrawler. Although fast, the search engine was restricted to simple searches and thus wasn't reliable. He developed SearchSavvy, which let users search up to 20 different search engines and directories at once. The first person to incorporate the idea of meta searching was Daniel Dreilinger of Colorado State University. Įxamples of metasearch engines include Skyscanner and, which aggregate search results of online travel agencies and provider websites and Searx, a free and open-source search engine which aggregates results from internet search engines. The process of fusion aims to improve the engineering of a metasearch engine. Problems such as spamming reduces the accuracy and precision of results. Sufficient data is gathered, ranked, and presented to the users. Metasearch engines take input from a user and immediately query search engines for results. A metasearch engine (or search aggregator) is an online information retrieval tool that uses the data of a web search engine to produce its own results.
