Perhaps you should try some spelling variations:
"literatura arte _ islam." » "literatura arabe _ islam.", "literatura breve _ islam.", "literatura entre _ islam."
"literatura de un islam." » "literatura de el islam.", "literatura de e islam."
"literatura de al islam." » "literatura de el islam.", "literatura de del islam.", "literatura de e islam."

You may be able to get more results by adjusting your search query.

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