• If you are trying to use Boolean operators, they must be ALL CAPS: %22pitt%((2c william) OR (2 william)) %((((21 1759) OR (1 1759))) OR (((21 1755) OR (21 1745))))-1806%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22pitt%((2c william) or (2 william)) %((((21 1759) or (1 1759))) or (((21 1755) OR (21 1745))))-1806%22".
• Adding a wildcard symbol may retrieve word variants: %22pitt%((2c william) or (2 william)) %((((21 1759) or (1 1759))) or (((21 1755) OR (21 1745))))-1806%22*.
