Perhaps you should try some spelling variations:
10 archaeometallurgy » 1 archaeometallurgy, 2.2 archaeometallurgy, social archaeometallurgy
2c archaeometallurgy » 2.2 archaeometallurgy, 1 archaeometallurgy, social archaeometallurgy

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: %22archaeology%((2c metallurgy) OR (27 metallurgy))%((2 maldi) OR (12 maldi))%2c thesis%((((2c archaeometallurgy) OR (((10 archaeometallurgy) OR (archaeometallurgy _))))) OR (_ archaeometallurgy))%2c metal%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22archaeology%((2c metallurgy) or (27 metallurgy))%((2 maldi) OR (12 maldi))%2c thesis%((((2c archaeometallurgy) or (((10 archaeometallurgy) or (archaeometallurgy _))))) or (_ archaeometallurgy))%2c metal%22".
• Adding a wildcard symbol may retrieve word variants: %22archaeology%((2c metallurgy) or (27 metallurgy))%((2 maldi) OR (12 maldi))%2c thesis%((((2c archaeometallurgy) or (((10 archaeometallurgy) or (archaeometallurgy _))))) or (_ archaeometallurgy))%2c metal%22*.
