Perhaps you should try some spelling variations:
2c archaeometallurgy » 2.2 archaeometallurgy, _ archaeometallurgy, 1 archaeometallurgy
c metallurgy » _ metallurgy, 4 metallurgy, 3 metallurgy
2 metallurgy » 27 metallurgy, 12 metallurgy, _ metallurgy
v metallurgy » _ metallurgy, 4 metallurgy, 27 metallurgy
12 maldi » 16 maldi, 17 maldi, _ maldi
2 maldi » 27 maldi, _ maldi, a maldi
c metal » sic metal, c methyl

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