• If you are trying to use Boolean operators, they must be ALL CAPS: (("literatura arabe et islam.") OR ((("literatura ni en islam.") OR ("literatura ii en islam."))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"literatura arabe et islam.\") or (((\"literatura ni en islam.\") OR (\"literatura ii en islam.\"))))*".
• Removing quotes may allow a broader search: (( literatura arabe et islam. ) or ((( literatura ni en islam. ) OR ( literatura ii en islam. ))))*.
