Google Search used to have the option to restrict search results to specific kinds of information such as forum pages, recipes, local places, blogs and patents. Those options are gone now, but Google Operating System shows how you can get the results back with a little URL hacking.
All you need to do is add a bit of text to the end of your search:
- Forum search: &tbm=dsc
- Recipe search: add &tbm=rcp
- Local search: add &tbm=plcs
- Blog search: add &tbm=blg
- Patent search: add &tbm=pts
If you miss having the ability to really hone your searches, the above trick should help.
