5.3 Serial Results

Both serial LSI++ search engines, lsiQuery and lsiBackend, fared well relative to lsiFinder, the search engine that uses the original Bellcore implementation of LSI. LsiQuery, which is designed to execute directly on the HTTP server, was between 5 and 10 times faster than lsiFinder on the four document collections tested. LsiBackend, designed to execute on a remote machine and communicate with the HTTP server through lsiRemote, showed similar performance gains over lsiFinder.
