• If you are trying to use Boolean operators, they must be ALL CAPS: %22polycarp %((((((5 saint) OR (15 saint))) OR (1 saint))) OR (((21 saint) OR (2 saint))))%((128 bishop) OR (21 bishop)) of smyrna%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22polycarp %((((((5 saint) or (15 saint))) or (1 saint))) or (((21 saint) OR (2 saint))))%((128 bishop) or (21 bishop)) of smyrna%22".
• Adding a wildcard symbol may retrieve word variants: %22polycarp %((((((5 saint) or (15 saint))) or (1 saint))) or (((21 saint) OR (2 saint))))%((128 bishop) or (21 bishop)) of smyrna%22*.
