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