Perhaps you should try some spelling variations:
2c archaeometallurgy » 2.2 archaeometallurgy, _ archaeometallurgy, 10 archaeometallurgy
1 archaeometallurgy » 10 archaeometallurgy, _ archaeometallurgy, 2.2 archaeometallurgy
2c thesis » a thesis, my thesis, i thesis

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