Perhaps you should try some spelling variations:
2c archaeometallurgy » 2.2 archaeometallurgy, _ archaeometallurgy, 1 archaeometallurgy
c metallurgy » _ metallurgy, 4 metallurgy, v metallurgy
12 maldi » 16 maldi, 17 maldi, _ maldi
25 main » 25 min, 25 mai, 25 marine
2 maldi » 27 maldi, _ maldi, a maldi
c metal » sic metal, c methyl
2 maii » 26 maii, 20 maii, 25 maii

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%((((((2 maldi) OR (12 maldi))) OR (2 maii))) OR (25 main))%a thesis%2c archaeometallurgy%c metal%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22archaeology%c metallurgy%((((((2 maldi) OR (12 maldi))) or (2 maii))) or (25 main))%a thesis%2c archaeometallurgy%c metal%22".
• Adding a wildcard symbol may retrieve word variants: %22archaeology%c metallurgy%((((((2 maldi) OR (12 maldi))) or (2 maii))) or (25 main))%a thesis%2c archaeometallurgy%c metal%22*.
