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