Perhaps you should try some spelling variations:
funcion administrativa » gestion administrativa
modelos economicos » modelo economico, modelos econometricos, delitos economicos
ciclos economicos » efectos economicos, socio economicos
ciclo economico » socio economico, modelo economico, socio economicos
para economico » para economia, amparo economico, marco economico
area economico » area economica, areas economica, areas economicas

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: "((\"funcion administrativa ((para economico) OR (area economico)) del derecho\") or (\"funcion administrativa ((ciclo economico) OR (((ciclos economicos) OR (modelos economicos)))) del derecho\"))".
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((\\"funcion administrativa ((para economico) OR (area economico)) del derecho\\") or (\\"funcion administrativa ((ciclo economico) or (((ciclos economicos) or (modelos economicos)))) del derecho\\"))\"".
• Removing quotes may allow a broader search: (( funcion administrativa ((para economico) OR (area economico)) del derecho ) or ( funcion administrativa ((ciclo economico) or (((ciclos economicos) or (modelos economicos)))) del derecho )).
