• If you are trying to use Boolean operators, they must be ALL CAPS: (("literatura e de islam.") OR ((("literatura gen de islam.") OR ("literatura gen del islam.")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"literatura e de islam.\") or (((\"literatura gen de islam.\") OR (\"literatura gen del islam.\"))))".
• Removing quotes may allow a broader search: (( literatura e de islam. ) or ((( literatura gen de islam. ) OR ( literatura gen del islam. )))).
