Forum search - Does not Like Numbers?

[tgutwin]

When I try to do a forum search for a number it gives me back "no results", when I know there are posts with the number string in them.

Example: search for - 2.6.21.5
I am looking for people that have upgraded their kernel to 2.6.21.5 and have problems with their bttv module.
I have also tried quoting the number string, same results.

If I google for that number string at zoneminder it gives me this result...

Maybe its a config thing. No biggie, just to let you know.
