enable 3-letters words in search

[tbworld]

Updated: I was full of crap. I forgot to alter the new mysql to handle full text searches. Works fine.

@nexum .. Works fine in vb4.20. Give JIRA a good check to see if it is a known issue, someone might have posted a fix.

My Test Conditions:
- vb4.2.0 (Unmodified, out of the box)
- Forum Only:
- words: mom dad IBM
- areas: title, post, tags
Rebuilt search indexes --- Just in case.
-----
Modified sql to handle 3 characters. <!-- Forgot this step

Currently on my board we use Sphinx. We wrote our own drivers for Sphinx and have been very pleased. Digital Point sells a Sphinx driver for VB, but I have not tested it, although I am sure it works.

Updated: Apparently vbulletin search can use 'and' 'or' - I probably wasn't familiar enough with vbulletin when I tested it way back then. Oh well! Sphinx has worked well for us.
