Perhaps you should try some spelling variations:
2c archaeometallurgy » 2.2 archaeometallurgy, _ archaeometallurgy, 1 archaeometallurgy
2c metallurgy » 27 metallurgy, 2 metallurgy, _ metallurgy
27 maldi » 17 maldi, 2 maldi, 7 maldi
2 thesis » 2 thess, 2 themes, 2 thesen
2c metal » c metal, ic metal, sc metal
2 theil » 2 theilen
2 mali » 2 maldi, 2 male, 2 maii

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%((2 mali) OR (27 maldi))%((2 thesis) OR (2 theil))%2c archaeometallurgy%2c metal%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22archaeology%2c metallurgy%((2 mali) or (27 maldi))%((2 thesis) OR (2 theil))%2c archaeometallurgy%2c metal%22".
• Adding a wildcard symbol may retrieve word variants: %22archaeology%2c metallurgy%((2 mali) or (27 maldi))%((2 thesis) OR (2 theil))%2c archaeometallurgy%2c metal%22*.
