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