• If you are trying to use Boolean operators, they must be ALL CAPS: %22archaeology%27 metallurgy%((2 maldi) OR (27 maldi))%((2c thesis) OR (a thesis))%1 archaeometallurgy%((((sc metal) OR (sic metal))) OR (c metal))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22archaeology%27 metallurgy%((2 maldi) or (27 maldi))%((2c thesis) or (a thesis))%1 archaeometallurgy%((((sc metal) OR (sic metal))) or (c metal))%22".
• Adding a wildcard symbol may retrieve word variants: %22archaeology%27 metallurgy%((2 maldi) or (27 maldi))%((2c thesis) or (a thesis))%1 archaeometallurgy%((((sc metal) OR (sic metal))) or (c metal))%22*.
