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
fe peru » de peru, del peru, use peru
luisa f » luisa de
de loa » de loja, de log, de lorca

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 fe peru luisa f ; ) OR ( condicion de campos ((de loa) OR (de los)) pau ; ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( edicion de fe peru luisa f ; ) or ( condicion de campos ((de loa) OR (de los)) pau ; ))~".
• Adding a wildcard symbol may retrieve word variants: (( edicion de fe peru luisa f ; ) or ( condicion de campos ((de loa) OR (de los)) pau ; ))*.
