Perhaps you should try some spelling variations:
2.2 archaeometallurgy » _ archaeometallurgy, social archaeometallurgy
10 archaeometallurgy » _ archaeometallurgy, archaeometallurgy _, social archaeometallurgy
1 archaeometallurgy » _ archaeometallurgy, archaeometallurgy _, _ archaeometallurgical
2c metallurgy » 27 metallurgy, 2 metallurgy, _ metallurgy
2c metal » c metal, ic metal, sc 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%2c metallurgy%((2 mali) OR (25 maii))%_ thesis%((((1 archaeometallurgy) OR (2.2 archaeometallurgy))) OR (10 archaeometallurgy))%2c metal%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22archaeology%2c metallurgy%((2 mali) or (25 maii))%_ thesis%((((1 archaeometallurgy) OR (2.2 archaeometallurgy))) or (10 archaeometallurgy))%2c metal%22".
• Adding a wildcard symbol may retrieve word variants: %22archaeology%2c metallurgy%((2 mali) or (25 maii))%_ thesis%((((1 archaeometallurgy) OR (2.2 archaeometallurgy))) or (10 archaeometallurgy))%2c metal%22*.
