Perhaps you should try some spelling variations:
2c archaeometallurgy » 2.2 archaeometallurgy, _ archaeometallurgy, 1 archaeometallurgy
2c metal » ic metal, sc metal, wc metal
c metal » sic metal, c methyl
2 maldi » 12 maldi, 27 maldi, _ maldi
25 maii » 25 mai, 25 main, 26 maii
2 mali » 2 male, 2 maii

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