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