Customizable features let you choose which areas of the Net to search, the number of returned links displayed, and the time MetaCrawler waits for responses from its targets. A unique Channel feature offers metasearches by specialized subjects from targeted sources. Among the metacrawler elite, ProFusion's special features distinguish it from the pack. Accessing nine directories and engines plus Usenet, it offers exceptionally broad customization options on its home page. The site returns a maximum of 175 unique hits ranked by relevancy and listed with site abstracts and tool attributions.
ProFusion supports searches by phrase, Boolean phrase, enforced terms, and parenthetical groupings.
Cass Brewer SavvySearch An access point for more than 200 search engines, guides, auctions, storefronts, Usenet and Netnews archives, and software libraries, SavvySearch is the broadest, most flexible metasearch tool out there. Choose 5 out of a pool of 23 engines to search simultaneously. Returns display site summaries, relevancy rankings, and tool attributions. Although it eliminates duplicate returns, SavvySearch notes which returns have multiple hits from its target engines. Unfortunately, you can't control the number of links returned, the time-out period for searches, the format of the returns, or how sites are sorted.
