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