Thanks for the reply Shabbir. The only problem I have with those commands is that I need the opposite. I need to get all of the search results minus the ones I don't want with those key words I said above. This is so because there is no common trigger words in the results that I want unlike the results I don't want... with the words CREDIT, INC. etc.
Also... are those commands simply put in the url text box? Because on my web browser nothing happens.
