Perhaps you should try some spelling variations:
funcion administrativa » gestion administrativa
valor economico » sector economico
costo economico » costos economicos, corte economico, cost economics
cali economico » cambio economico, ciclo economico, campo economico
caso economico » censo economico, campo economico, cambio economico

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