• If you are trying to use Boolean operators, they must be ALL CAPS: "((storia delle) OR (storia del)) idee ((de delle) OR (de dolle)) istituzioni (politiche" or politischer").
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((storia delle) or (storia del)) idee ((de delle) OR (de dolle)) istituzioni (politiche\" or politischer\")".
• Removing quotes may allow a broader search: ((storia delle) or (storia del)) idee ((de delle) OR (de dolle)) istituzioni (politiche or politischer ).
• Adding a wildcard symbol may retrieve word variants: "((storia delle) or (storia del)) idee ((de delle) OR (de dolle)) istituzioni (politiche" or politischer")*.
