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