In the top "Find Results" section you put your search term.
In the 2nd section, 7th line, is the "Domain" option. Put in:
betterthandiamond.com
Then at the top click "Google Search". It will search only this site for your term. It will return pages on this site other than the message board, but I thought it would help in the meantime...
