Perhaps you should try some spelling variations:
campo mahler » campo javier
edicion del » medicion del, edicion de, medicion de
del casos » de casos, del caso, diez casos
casos per » casas per, casos para, casos de
edicion e » edicion de, edicion en, medicion e
mahler la » mahler una, taller la, mahlke la
e campo » el campo, de campo, en campo
per la » poder la
la pau » la 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: (( edicion del casos per la pau ; ) OR ( edicion e campo mahler la pau ; ))~.
• Adding a wildcard symbol may retrieve word variants: (( edicion del casos per la pau ; ) or ( edicion e campo mahler la pau ; ))*.
