2c thesis » 2 thesis, _ thesis, a thesis
sc metal » sic metal, c metal, ic metal
2 maldi » 12 maldi, 27 maldi, _ maldi

• If you are trying to use Boolean operators, they must be ALL CAPS: %22archaeology%sc metallurgy%((((2 mali) OR (2 maldi))) OR (2 maii))%2c thesis%_ archaeometallurgy%sc metal%22.
• Adding a wildcard symbol may retrieve word variants: %22archaeology%sc metallurgy%((((2 mali) or (2 maldi))) or (2 maii))%2c thesis%_ archaeometallurgy%sc metal%22*.
