• If you are trying to use Boolean operators, they must be ALL CAPS: %22polycarp %((((((2f saint) OR (25 saint))) OR (((((2 saint) OR (2 salient))) OR (1 saint))))) OR (((21 saint) OR (2015 saint))))%((((2c bishop) OR (21 bishop))) OR (r.c bishop)) of smyrna%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22polycarp %((((((2f saint) OR (25 saint))) or (((((2 saint) or (2 salient))) or (1 saint))))) or (((21 saint) or (2015 saint))))%((((2c bishop) or (21 bishop))) or (r.c bishop)) of smyrna%22".
• Adding a wildcard symbol may retrieve word variants: %22polycarp %((((((2f saint) OR (25 saint))) or (((((2 saint) or (2 salient))) or (1 saint))))) or (((21 saint) or (2015 saint))))%((((2c bishop) or (21 bishop))) or (r.c bishop)) of smyrna%22*.
