SPHYNX search not picking up words within URLs - Please help

[SDB]

Hi All

Due to the huge size of our database, and trying everything else, we've had to move to Sphynx search to stop our board grinding to a halt whenever someone searches (which happens regularly).

This has transformed the speed of the site. But...

Its flakey.

Current problem, is that it doesn't appear to be returning results if the search term is part of a url, either the url itself or the descriptive part.

Eg.. the vBCode would read :

Welcome to the test site

If I search for "test", the post is not returned.

But posts with "test" in the main body ARE returned.

Any help with this would be greatly appreciated.

Simon
