Perhaps you should try some spelling variations:
2c thesis » 2 thesis, _ thesis, a thesis
ic metal » sic metal, tic metal, sc metal
c metal » sic metal, c methyl
2 male » 2 make
2 maii » 26 maii, 20 maii, 25 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%_ metallurgy%((2 male) OR (2 maii))%2c thesis%_ archaeometallurgy%((ic metal) OR (c metal))%22.
• Adding a wildcard symbol may retrieve word variants: %22archaeology%_ metallurgy%((2 male) or (2 maii))%2c thesis%_ archaeometallurgy%((ic metal) or (c metal))%22*.
