Perhaps you should try some spelling variations:
2c archaeometallurgy » 2.2 archaeometallurgy, 10 archaeometallurgy, social archaeometallurgy
1 archaeometallurgy » 10 archaeometallurgy, 2.2 archaeometallurgy, archaeometallurgy _
_ archaeometallurgy » _ archaeometallurgical, archaeometallurgy _
2c thesis » 2 thesis, a thesis, my thesis
2c metal » ic metal, sc metal, wc metal

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 metal) OR (c metal))lurgy%2 maldi%((2c thesis) OR (_ thesis))%((((2c archaeometallurgy) OR (1 archaeometallurgy))) OR (_ archaeometallurgy))%((2c metal) OR (c metal))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22archaeology%((2c metal) OR (c metal))lurgy%2 maldi%((2c thesis) or (_ thesis))%((((2c archaeometallurgy) or (1 archaeometallurgy))) or (_ archaeometallurgy))%((2c metal) OR (c metal))%22".
• Adding a wildcard symbol may retrieve word variants: %22archaeology%((2c metal) OR (c metal))lurgy%2 maldi%((2c thesis) or (_ thesis))%((((2c archaeometallurgy) or (1 archaeometallurgy))) or (_ archaeometallurgy))%((2c metal) OR (c metal))%22*.
