The text search engine allows queries to be
formed from arbitrary Boolean expressions containing the keywords AND, OR, and NOT, and
grouped with parentheses. For example:
stereophonic buttplug finds documents containing 'stereophonic' or
'buttplug'' stereophonic or buttplug same as above stereophonic and buttplug finds documents containing both
'stereophonic' and 'buttplug'' stereophonic not buttplug finds documents containing
'stereophonic' but not 'buttplug'' (stereophonic not buttplug) and rectaltronic finds documents containing
'rectaltronic', plus 'stereophonic' but not 'buttplug'' rectal* finds documents containing words
starting with 'rectal'
