Perhaps you should try some spelling variations:
2c thesis » 2 thesis, _ thesis, a thesis
2c metal » c metal, ic metal, sic metal
wc metal » c metal, ic metal, sic metal
sc metal » sic metal, c metal, ic metal
27 maldi » 17 maldi, 2 maldi, 7 maldi

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 (wc metal))) OR (sc metal))lurgy%27 maldi%2c thesis%_ archaeometallurgy%((((2c metal) OR (wc metal))) OR (sc metal))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22archaeology%((((2c metal) OR (wc metal))) or (sc metal))lurgy%27 maldi%2c thesis%_ archaeometallurgy%((((2c metal) OR (wc metal))) or (sc metal))%22".
• Adding a wildcard symbol may retrieve word variants: %22archaeology%((((2c metal) OR (wc metal))) or (sc metal))lurgy%27 maldi%2c thesis%_ archaeometallurgy%((((2c metal) OR (wc metal))) or (sc metal))%22*.
