Search Tools Product Reports


"Wide Area Information Server" search engine based on parallel processing search algorithms developed at Thinking Machines in the 1980s. Free source makes this a widely used engine, although I personally don't like the default relevance rankings in the results.

Warning: While this was pioneering software, it shows no continuing development. It does not include modern search features and is not appropriate for new projects. Old versions of WAIS may not be Y2K-compliant: if you're running it, check your code.
