Perhaps you should try some spelling variations:
2c archaeometallurgy » 2.2 archaeometallurgy, _ archaeometallurgy, 1 archaeometallurgy
10 metallurgy » 27 metallurgy, v metallurgy
4 metallurgy » v metallurgy, 27 metallurgy
2c thesis » 2 thesis, _ thesis, a thesis
12 maldi » 16 maldi, 17 maldi, _ maldi
2c metal » c metal, ic metal, sc metal
2 maldi » 27 maldi, _ maldi, a maldi

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%((((10 metallurgy) OR (4 metallurgy))) OR (_ metallurgy))%((2 maldi) OR (12 maldi))%2c thesis%2c archaeometallurgy%2c metal%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22archaeology%((((10 metallurgy) or (4 metallurgy))) or (_ metallurgy))%((2 maldi) OR (12 maldi))%2c thesis%2c archaeometallurgy%2c metal%22".
• Adding a wildcard symbol may retrieve word variants: %22archaeology%((((10 metallurgy) or (4 metallurgy))) or (_ metallurgy))%((2 maldi) OR (12 maldi))%2c thesis%2c archaeometallurgy%2c metal%22*.
