How about adding something like
Search for keywords:
Place + in front of a word which must be found and - in front of a word which must not be found. Put a list of words separated by | into brackets if only one of the words must be found. Use * as a wildcard for partial matches.
Or even something like
Search for all terms or use query as entered
Search for any terms
Would return better results.
