2c metal » c metal, sc metal, wc metal
ic metal » sic metal, tic metal, c metal

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 (ic metal))lurgy) OR (_ metallurgy))%12 maldi%((2 thesis) OR (2 themes))%2c archaeometallurgy%((2c metal) OR (ic metal))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22archaeology%((((2c metal) OR (ic metal))lurgy) or (_ metallurgy))%12 maldi%((2 thesis) or (2 themes))%2c archaeometallurgy%((2c metal) OR (ic metal))%22".
• Adding a wildcard symbol may retrieve word variants: %22archaeology%((((2c metal) OR (ic metal))lurgy) or (_ metallurgy))%12 maldi%((2 thesis) or (2 themes))%2c archaeometallurgy%((2c metal) OR (ic metal))%22*.
