• If you are trying to use Boolean operators, they must be ALL CAPS: %22archaeology%27 metallurgy%((2 maldi) OR (17 maldi))%2c 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 (17 maldi))%2c 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 (17 maldi))%2c thesis%1 archaeometallurgy%((((sc metal) OR (sic metal))) or (c metal))%22*.
