You can tell Google to only show you results from a particular site or sites.
For example, here is how I showed my students this afternoon how to search for info on store cards and narrow it down to only include Australian web sites:
"store cards" site:.au
This means search for the string in that order and only with a space in between, the site: bit means only show results for web sites that end in .au
If you want to search using Google but only search QB, you'd add "site:www.quiltingboard.com". The possibilities extend to anything in between. For Aus Gov't sites "site:.gov.au" etc.
Told the students (VCAL numeracy) it was probably the most useful thing they would ever learn in my subject
