Perhaps you should try some spelling variations:
funcion administrativa » gestion administrativa
amparo economico » impacto economico, marco economico, ambito economico
administrativa y » administrativa de
para economico » area economico, para economia, marco economico
economico del » economico de
y economico » y economica, y economia

You may be able to get more results by adjusting your search query.

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