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