Perhaps you should try some spelling variations:
2c thesis » 2 thesis, _ thesis, a thesis
ic metal » sic metal, tic metal, c metal
sc metal » sic metal, c metal, arc metal
wc metal » c metal, sic metal, arc metal
2 maldi » 12 maldi, 27 maldi, _ 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%((ic metal) OR (((sc metal) OR (wc metal))))lurgy%2 maldi%2c thesis%_ archaeometallurgy%((ic metal) OR (((sc metal) OR (wc metal))))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22archaeology%((ic metal) or (((sc metal) OR (wc metal))))lurgy%2 maldi%2c thesis%_ archaeometallurgy%((ic metal) or (((sc metal) OR (wc metal))))%22".
• Adding a wildcard symbol may retrieve word variants: %22archaeology%((ic metal) or (((sc metal) OR (wc metal))))lurgy%2 maldi%2c thesis%_ archaeometallurgy%((ic metal) or (((sc metal) OR (wc metal))))%22*.
