Perhaps you should try some spelling variations:
literature arab » literature arts, literature art, literature ararat
literature more » literature modern, literature many, literature middle
literatura arab » literatura oral, literatura artes, literatura a
agenda _i » agenda bis, agenda 21, agenda a
1 agenda » 7 agenda, 3 agenda, 1 agency
_ agenda » _ agent, _ agents, _ agency

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: (( 1 agenda _ a literature more ) OR ( _ agenda _i _ ((literature arab) OR (literatura arab)) ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( 1 agenda _ a literature more ) or ( _ agenda _i _ ((literature arab) OR (literatura arab)) ))*".
