• If you are trying to use Boolean operators, they must be ALL CAPS: %22archaeology%c metallurgy%((((((2 maldi) OR (27 maldi))) OR (26 maii))) OR (25 mai))%a thesis%_ archaeometallurgy%c metal%22.
• Adding a wildcard symbol may retrieve word variants: %22archaeology%c metallurgy%((((((2 maldi) or (27 maldi))) or (26 maii))) or (25 mai))%a thesis%_ archaeometallurgy%c metal%22*.
