Perhaps you should try some spelling variations:
condicion de » condiciones de
edicion de » medicion de
peru luisa » peru luis, peru lima, pare luisa
de campos » de campo, de caminos, de cambios
use peru » abuse peru, de peru, fe peru
luisa f » luisa de
loa pau » la pau
de use » de muse, de usme, de uso
de loa » de loja, de los, de log

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: (( edicion de use peru luisa f ; ) OR ( condicion de campos de loa pau ; ))~.
• Adding a wildcard symbol may retrieve word variants: (( edicion de use peru luisa f ; ) or ( condicion de campos de loa pau ; ))*.
