Perhaps you should try some spelling variations:
2c archaeometallurgy » 2.2 archaeometallurgy, _ archaeometallurgy, 1 archaeometallurgy
ic metallurgy » i metallurgy, ii metallurgy, zinc metallurgy
2c thesis » 2 thesis, _ thesis, my thesis
12 maldi » 16 maldi, 17 maldi, 12 mai
ic metal » sic metal, tic metal, c metal
2 maldi » 27 maldi, a maldi, 2 maedi

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