Perhaps you should try some spelling variations:
literatura peruana » literatura espana, literatura mexicana, literatura alemana
literatura arabe » literatura breve, literatura de, literatura e
literatura para » literatura al, literatura a, literatura cubana
e islas » el islam
arabe e » arabes e, arabe de, arabe en
e islam » el islam, del 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 para) OR (literatura peruana)) e islas.\") or (\"literatura arabe e islam.\"))~".
• Removing quotes may allow a broader search: (( ((literatura para) or (literatura peruana)) e islas. ) or ( literatura arabe e islam. ))~.
