Perhaps you should try some spelling variations:
2c archaeometallurgy » 2.2 archaeometallurgy, 1 archaeometallurgy, 10 archaeometallurgy
_ archaeometallurgy » _ archaeometallurgical, archaeometallurgy _
c metallurgy » _ metallurgy, v metallurgy, 2 metallurgy
4 metallurgy » _ metallurgy, v metallurgy, 27 metallurgy
a thesis » _ thesis
2 maldi » 12 maldi, 27 maldi, _ maldi
c metal » sic metal, c methyl

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%((c metallurgy) OR (4 metallurgy))%2 maldi%a thesis%((2c archaeometallurgy) OR (_ archaeometallurgy))%c metal%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22archaeology%((c metallurgy) OR (4 metallurgy))%2 maldi%a thesis%((2c archaeometallurgy) or (_ archaeometallurgy))%c metal%22".
• Adding a wildcard symbol may retrieve word variants: %22archaeology%((c metallurgy) OR (4 metallurgy))%2 maldi%a thesis%((2c archaeometallurgy) or (_ archaeometallurgy))%c metal%22*.
