Perhaps you should try some spelling variations:
conditions et » conditions _, conditions 20th, conditions 21st
edicion el » edicion del, edicion en, edicion e
campus per » campus de
et campos » en campos, e campos, de campos
el campus » el campo, el corpus
del las » del la, del los, del laser
del lao » del lago, del lado, del lazo
per el » ser el, per al, per il
pasado » basado

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: (( conditions et campos ((del las) OR (del lao)) pau ; ) OR ( edicion el campus per el pasado ; ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( conditions et campos ((del las) OR (del lao)) pau ; ) or ( edicion el campus per el pasado ; ))~".
• Adding a wildcard symbol may retrieve word variants: (( conditions et campos ((del las) OR (del lao)) pau ; ) or ( edicion el campus per el pasado ; ))*.
