2a saint » 2 saint, 21 saint, la saint
25 saint » 5 saint, 15 saint, 2015 saint

• If you are trying to use Boolean operators, they must be ALL CAPS: %22polycarp %((((((2f saint) OR (2a saint))) OR (((25 saint) OR (((14 saint) OR (1 saint))))))) OR (a saint))%f.r.s bishop of smyrna%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22polycarp %((((((2f saint) or (2a saint))) or (((25 saint) or (((14 saint) OR (1 saint))))))) or (a saint))%f.r.s bishop of smyrna%22".
• Adding a wildcard symbol may retrieve word variants: %22polycarp %((((((2f saint) or (2a saint))) or (((25 saint) or (((14 saint) OR (1 saint))))))) or (a saint))%f.r.s bishop of smyrna%22*.
