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