Perhaps you should try some spelling variations:
sanciones administrativas » actos administrativos, manuales administrativos
funcion administrativa » gestion administrativa
costo economico » costos economicos, corte economico, cost economics
ciclo economico » ciclos economicos, socio economico, modelo economico
caso economico » censo economico, campo economico, cambio economico
cali economico » cambio economico, campo economico, lo 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 ((caso economico) OR (costo economico)) del derecho\") or (\"sanciones administrativas ((cali economico) OR (ciclo economico)) del derecho\"))".
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((\\"funcion administrativa ((caso economico) OR (costo economico)) del derecho\\") or (\\"sanciones administrativas ((cali economico) or (ciclo economico)) del derecho\\"))\"".
• Removing quotes may allow a broader search: (( funcion administrativa ((caso economico) OR (costo economico)) del derecho ) or ( sanciones administrativas ((cali economico) or (ciclo economico)) del derecho )).
