Perhaps you should try some spelling variations:
2c archaeometallurgy » 2.2 archaeometallurgy, _ archaeometallurgy, 1 archaeometallurgy
zinc metallurgy » mine metallurgy, mines metallurgy, i metallurgy
sic metallurgy » i metallurgy, ii metallurgy, vii metallurgy
sic metal » c metal
16 maldi » 12 maldi, 17 maldi, _ maldi
a thesis » _ thesis
2 maldi » 12 maldi, 27 maldi, _ maldi
6 maldi » _ maldi, a maldi, 4 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%((sic metallurgy) OR (zinc metallurgy))%((2 maldi) OR (((16 maldi) OR (6 maldi))))%a thesis%2c archaeometallurgy%sic metal%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22archaeology%((sic metallurgy) OR (zinc metallurgy))%((2 maldi) or (((16 maldi) or (6 maldi))))%a thesis%2c archaeometallurgy%sic metal%22".
• Adding a wildcard symbol may retrieve word variants: %22archaeology%((sic metallurgy) OR (zinc metallurgy))%((2 maldi) or (((16 maldi) or (6 maldi))))%a thesis%2c archaeometallurgy%sic metal%22*.
