Perhaps you should try some spelling variations:
2c archaeometallurgy » 2.2 archaeometallurgy, _ archaeometallurgy, 1 archaeometallurgy
2c thesis » 2 thesis, _ thesis, a thesis
c methyl » _ methyl, n methyl, 2 methyl
c metal » sic metal
2 mali » 2 maldi, 2 male
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%((2((c metal) OR (c methyl))) OR (((c metal) OR (c methyl))))lurgy%((2 mali) OR (2 maii))%2c thesis%2c archaeometallurgy%((2((c metal) OR (c methyl))) OR (((c metal) OR (c methyl))))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22archaeology%((2((c metal) OR (c methyl))) or (((c metal) OR (c methyl))))lurgy%((2 mali) or (2 maii))%2c thesis%2c archaeometallurgy%((2((c metal) OR (c methyl))) or (((c metal) OR (c methyl))))%22".
• Adding a wildcard symbol may retrieve word variants: %22archaeology%((2((c metal) OR (c methyl))) or (((c metal) OR (c methyl))))lurgy%((2 mali) or (2 maii))%2c thesis%2c archaeometallurgy%((2((c metal) OR (c methyl))) or (((c metal) OR (c methyl))))%22*.
