Perhaps you should try some spelling variations:
sic metal » c metal
sc metal » c metal, ic metal, wc metal
a thesis » _ thesis
25 maii » 25 mai, 25 main, 26 maii
2 mali » 2 maldi, 2 male
2 maii » 26 maii, 20 maii, 28 maii

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