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"
