• If you are trying to use Boolean operators, they must be ALL CAPS: %22archaeology%((2c metal) OR (sc metal))lurgy%((2 male) OR (((25 maii) OR (25 mai))))%((2c thesis) OR (2 thesis))%((2c archaeometallurgy) OR (_ archaeometallurgy))%((2c metal) OR (sc metal))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22archaeology%((2c metal) or (sc metal))lurgy%((2 male) or (((25 maii) or (25 mai))))%((2c thesis) or (2 thesis))%((2c archaeometallurgy) OR (_ archaeometallurgy))%((2c metal) or (sc metal))%22".
• Adding a wildcard symbol may retrieve word variants: %22archaeology%((2c metal) or (sc metal))lurgy%((2 male) or (((25 maii) or (25 mai))))%((2c thesis) or (2 thesis))%((2c archaeometallurgy) OR (_ archaeometallurgy))%((2c metal) or (sc metal))%22*.
