BTDubs to @
faithfool, I believe the google terms you want to enter are:
Code:
site:boards.straightdope.com "view single post" "find all posts by faithfool" "og"
Adding "AND" doesn't do anything, as far as I know. Putting things in quotes forces them to be required, exact search terms, which is important even for "og" because if you don't make it exact, google will decide you may have meant "of" and show you those results too. I used "find all posts by faithfool" in place of your location text because it makes it easier to do this search for any username without knowing their location.
