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