TIP: Use + and - before your keywords to match only pages with (or without) the words in them.
For example, "+cat -dog" will match all the pages with "cat" and without "dog". You can require
an entire phrase by putting it in quotation marks: "the cat" To require or prevent pages with
phrases, put the +/- inside or outside the quotation marks: i.e. +"the cat" or "+the cat" or
-'the dog' or "-the dog"
