Tip: Use + before 'must' words, - before 'not' words

How to use the search function:

• normal searching can just be keywords,
  ie 'bill gates' (returns any page with one of those words)

• for words you *must*  have,  add a '+',
  ie 'bill +gates scripts' (returns any page with gates. Pages with bill will be returned first. If 'gates' is not found in
  any pages, no results will be returned.)

• for words you *can't* have, add a '-',
  ie 'bill -gates' (returns any page with bill, but not gates. If a 'good' page
  also has bill, it's returned first.
