Perhaps you should try some spelling variations:
literatura delspana » literatura espana, literatura hispana, literatuta espana
literatura del » literatura de, literatura en
delspana en » espana en
en islam » el islam, un islam, en ilam
e islam » el islam, del islam
e islas » el 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 del ((e islam) OR (e islas)).\") or (\"literatura delspana en islam.\"))".
• Removing quotes may allow a broader search: (( literatura del ((e islam) or (e islas)). ) or ( literatura delspana en islam. )).
