Perhaps you should try some spelling variations:
2c archaeometallurgy » 2.2 archaeometallurgy, _ archaeometallurgy, 1 archaeometallurgy
ii metallurgy » vii metallurgy, i metallurgy, ii metallurgie
ic metallurgy » i metallurgy, zinc metallurgy, its metallurgy
a thesis » _ thesis
ic metal » sic metal, tic metal, c metal
12 maldi » 16 maldi, 17 maldi, _ maldi
2 thesis » 2 thess, 2 thesen, 2 theil
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%((ic metallurgy) OR (ii metallurgy))%((2 maldi) OR (12 maldi))%((2 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) OR (ii metallurgy))%((2 maldi) or (12 maldi))%((2 thesis) or (a thesis))%2c archaeometallurgy%ic metal%22".
• Adding a wildcard symbol may retrieve word variants: %22archaeology%((ic metallurgy) OR (ii metallurgy))%((2 maldi) or (12 maldi))%((2 thesis) or (a thesis))%2c archaeometallurgy%ic metal%22*.
