Comparison 1 Introduction This article provides information on searching the Internet using Multi-search engines, rather than individual search engines, discusses the theory of how these things work, their advantages and disadvantages and finally presents the reader with a small tabular comparison of some major Multi-search engines. Why use a Multi-search engine? Metasearch engine A metasearch engine is a search tool[1][2] 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 process of fusion also improves the search results.[3] 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.

Disco Hyperdata Browser The Disco - Hyperdata Browser is a simple browser for navigating the Semantic Web as an unbound set of data sources. The browser renders all information, that it can find on the Semantic Web about a specific resource, as an HTML page. This resource description contains hyperlinks that allow you to navigate between resources. While you move from resource to resource, the browser dynamically retrieves information by dereferencing HTTP URIs and by following rdfs:seeAlso links. News Comparison 2 How to get the best out of the Internet. Since the last time that I wrote this article there have been a great many changes with the major search engines and what they can do. This provides a comparison of major engines. Previous versions of this article have included various different search engines, and this continues to be the case here; I add and drop search engines as they come into or go out of fashion.

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. They tend to return results from smaller and/or free search engines and miscellaneous free directories, often small and highly commercial. 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.

Vista on Future Wolfram Alpha isn't the "Google killer" that many hyped it up to be prior to its 2009 launch. Instead, the self-described computational knowledge engine takes a completely different approach to letting users find and analyze information. Rather than scouring the Web and ranking everybody's pages in the order it thinks we'd find them useful, it uses its own data sets and computational power to return detailed reports and analysis about whatever topics users query it for. Tomorrow, the service will ramp things up a notch when its "pro" version launches. For $5 per month, Wolfram Alpha Pro will allow users to do way more with its data, as well as enable them to upload their own. The premium offering will be discounted for students and enterprise users.
