• If you are trying to use Boolean operators, they must be ALL CAPS: ((frances OR francesc) OR france) ((((polo OR roles) OR (prol OR prof)) OR polit) OR rolt) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((frances or francesc) or france) ((((polo or roles) or (prol OR prof)) or polit) or rolt) ;~".
• Adding a wildcard symbol may retrieve word variants: ((frances or francesc) or france) ((((polo or roles) or (prol OR prof)) or polit) or rolt) ;*.
