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:
ice skating
finds documents containing 'ice' or 'skating'
ice or skating
same as above (finds documents containing 'ice' or
'skating')
ice and skating
finds documents containing both 'ice' and 'skating'
skating not roller
finds documents containing 'skating' but not
'roller'
(skating not roller) and ice
finds documents containing 'ice', plus 'skating' but
not 'roller'
pro*
finds documents containing words starting with 'pro'
