A web search engine is a software system that is
designed to search for information on the World Wide Web. The search results
are generally presented in a line of results, often referred to as search
engine results pages (SERPs). The information may be a mix of web pages, images
and other types of files. Some search engines also mine data available in
databases or open directories. Unlike web directories, which are maintained
only by human editors, search engines also maintain real-time information by
running an algorithm on a web crawler. Internet content that is not capable of
being searched by a web search engine is generally described as the deep web.
S
earch engines and directories are both tools people
use to find information on the Web. The difference is in how they get and
organize their information. Search engines use little programs called spiders
or bots that scour the Internet, follow links, and bring back this information
to the search engine's index.
A metasearch engine (or aggregator) is a search
tool that uses another search engine's data to produce its own results from the
Internet. Metasearch engines take input from a user and simultaneously send out
queries to third party search engines for results.
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. For example, Dogpileis a metasearch engine.
