• If you are trying to use Boolean operators, they must be ALL CAPS: %22archaeology%((((2 metallurgy) OR (4 metallurgy))) OR (_ metallurgy))%12 maldi%2c thesis%2c archaeometallurgy%c metal%22.
• Adding a wildcard symbol may retrieve word variants: %22archaeology%((((2 metallurgy) or (4 metallurgy))) or (_ metallurgy))%12 maldi%2c thesis%2c archaeometallurgy%c metal%22*.
