UBB.threads PHP Forum Software Community Forums UBB.threads 6 Version 6 Support google indexing

Hi,
I just have a question about the state of google's indexing of my forum.
I did the following seach in Google:
"ubbthreads site:superiorpics.com"
in the hope that I would locate all indexed pages from my forum at http://www.superiorpics.com/ubbthreads/ubbthreads.php

What I came up with was only 40 or 50 pages of topics that had been indexed, along with a whole lot of links such as
www.superiorpics.com/ubbthreads/showday.php?Cat=0&day=30&month=12&year=2004
and
www.superiorpics.com/ubbthreads/printthread.php/Board/91/main/649870/type/post

and that was it!
I have many tens of thousands of links that should be indexed here, so what do you think is happening here?
thanks

Your query is not really good.

Try this:
http://www.google.com/search?q=inurl:superiorpics.com/ubbthreads&filter=0

Thanks! That did the trick
