sic metal » c metal
2c thesis » 2 thesis, _ thesis, a thesis
ic metal » tic metal, c metal, sc 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%((ic metal) OR (sic metal))lurgy%((2 mali) OR (25 maii))%2c thesis%2c archaeometallurgy%((ic metal) OR (sic metal))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22archaeology%((ic metal) OR (sic metal))lurgy%((2 mali) or (25 maii))%2c thesis%2c archaeometallurgy%((ic metal) OR (sic metal))%22".
• Adding a wildcard symbol may retrieve word variants: %22archaeology%((ic metal) OR (sic metal))lurgy%((2 mali) or (25 maii))%2c thesis%2c archaeometallurgy%((ic metal) OR (sic metal))%22*.
