Unlike search engines, the metasearchers and metacrawlers do not search the web themselves. Instead, they send the searches out to several engines at once. We have provided a table showing the characteristics of some of the major metasearchers. Their scope differs, as do the ways in which the results are blended and displayed. MetaFind has links to Dogpile , which sends your query to directories and specialty search sites as well as to the search engines.
Most metasearch engines have commercial backing.
Those that do not, such as SavvySearch , can be difficult to reach or use because they may lack the extra hardware support that these search tools need. You may also be interested in looking at OneSeek , which was launched in January this year.
