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