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