Perhaps you should try some spelling variations:
ediciones de » condiciones de
campo urbano » cambio urbano, casco urbano, caso urbano
cano carlos » caro carlos, campo carlos, cairo carlos
edicion de » medicion de
de campo » de cambio, el campo
urbano a » urbano y, urbano una, urbano de
a papa » la papa, al papa, a para
a paz » la paz, ma paz, y paz

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: (( ediciones de campo urbano a papa ; ) OR ( ((edicion y) OR (edicion de)) cano carlos a paz ; ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ediciones de campo urbano a papa ; ) or ( ((edicion y) OR (edicion de)) cano carlos a paz ; ))~".
• Adding a wildcard symbol may retrieve word variants: (( ediciones de campo urbano a papa ; ) or ( ((edicion y) OR (edicion de)) cano carlos a paz ; ))*.
