• If you are trying to use Boolean operators, they must be ALL CAPS: %22archaeology%27 metallurgy%2 maldi%a thesis%((2.2 archaeometallurgy) OR (_ archaeometallurgy))%((ssic metal) OR (sic metal))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22archaeology%27 metallurgy%2 maldi%a thesis%((2.2 archaeometallurgy) OR (_ archaeometallurgy))%((ssic metal) or (sic metal))%22".
• Adding a wildcard symbol may retrieve word variants: %22archaeology%27 metallurgy%2 maldi%a thesis%((2.2 archaeometallurgy) OR (_ archaeometallurgy))%((ssic metal) or (sic metal))%22*.
