Options and hints on the alta-vista style search facility

The search engine currently supports the following alta-vista style searches:
OR searches
If you type
  TIE YOUR MOTHER DOWN
as the search then it will return a list of all songs containing any of the words (TIE or YOUR or MOTHER or DOWN)
AND searches
Put a + before any word to insist that songs returned must contain at least one instance of that word:
  TIE YOUR +MOTHER DOWN
This would search for ((TIE or YOUR or DOWN) and MOTHER)
ADJACENT searches
Put words between double quotes to insist that the songs returned contain those words next to each other:
  TIE YOUR "MOTHER DOWN"
This would search for (TIE or YOUR or MOTHER DOWN)
COMBINATION searches
Mix and match as required:
  +TIE +"YOUR MOTHER" DOWN UP
This would search for ((TIE and YOUR MOTHER) with DOWN or UP)
The score returned is based on the number of matches found.

At the moment, the search engine isn't very tolerant of malformed queries and will probably return wrong results if you type something unexpected. I will fix this in due course.
