• If you are trying to use Boolean operators, they must be ALL CAPS: (( 1 amandi ((libri e) OR (libri x)) letteratura araba ) OR ( i gran libro de litterature sarda )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( 1 amandi ((libri e) OR (libri x)) letteratura araba ) or ( i gran libro de litterature sarda ))".
• Adding a wildcard symbol may retrieve word variants: (( 1 amandi ((libri e) OR (libri x)) letteratura araba ) or ( i gran libro de litterature sarda ))*.
