Perhaps you should try some spelling variations:
ic metallurgy » i metallurgy, ii metallurgy, zinc metallurgy
2c thesis » _ thesis, my thesis, i thesis
12 maldi » 16 maldi, 17 maldi, 2 maldi
2 thesis » 2 thess, 2 theil, 2 themes
ic metal » sic metal, tic metal, c 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%ic metallurgy%12 maldi%((((2c thesis) OR (2 thesis))) OR (a thesis))%_ archaeometallurgy%ic metal%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22archaeology%ic metallurgy%12 maldi%((((2c thesis) OR (2 thesis))) or (a thesis))%_ archaeometallurgy%ic metal%22".
• Adding a wildcard symbol may retrieve word variants: %22archaeology%ic metallurgy%12 maldi%((((2c thesis) OR (2 thesis))) or (a thesis))%_ archaeometallurgy%ic metal%22*.
