• If you are trying to use Boolean operators, they must be ALL CAPS: %22pitt%((2c william) OR (2 william)) %((((2((1 1759) OR (17 1759))) OR (((1 1759) OR (17 1759))))) OR (21 1755))-1806%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22pitt%((2c william) or (2 william)) %((((2((1 1759) OR (17 1759))) or (((1 1759) OR (17 1759))))) or (21 1755))-1806%22".
• Adding a wildcard symbol may retrieve word variants: %22pitt%((2c william) or (2 william)) %((((2((1 1759) OR (17 1759))) or (((1 1759) OR (17 1759))))) or (21 1755))-1806%22*.
