• If you are trying to use Boolean operators, they must be ALL CAPS: (((("literatura ma y islam.") OR ("literatura o de islam."))) OR ("literature arab _ isla."))~.
• Removing quotes may allow a broader search: (((( literatura ma y islam. ) or ( literatura o de islam. ))) or ( literature arab _ isla. ))~.
• Adding a wildcard symbol may retrieve word variants: (((("literatura ma y islam.") or ("literatura o de islam."))) or ("literature arab _ isla."))*.
