SearchDay - AltaVista Testing "Paraphrase" Tool - 16 April 2002
AltaVista Testing "Paraphrase" Tool

AltaVista's new query refinement tool offers suggestions for improving your search terms. Also, the search engine is adding new content on a more frequent basis.

The new query refinement tool is called "Paraphrase," offering up to a dozen alternate search queries with a click of a link. Paraphrase results are located immediately under the search box on the results page.

Paraphrase terms are more than just new search terms, however. They represent topic categories within the result set that offer suggestions for focusing and refining the search, and in some cases suggest an entirely new search expression.
