Perhaps you should try some spelling variations:
sanciones administrativas » funcion administrativa, actos administrativos, manuales administrativos
sanciones administrativa » sancion administrativa, funciones administrativas, acciones administrativas
jogos economicos » juegos economicos, costos economicos, modelos economicos
el derechos » en derechos, de derechos, 1 derechos
el derecho » del derecho

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: ((sanciones administrativa) OR (sanciones administrativas)) jogos economicos ((el derechos) OR (el derecho))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((sanciones administrativa) or (sanciones administrativas)) jogos economicos ((el derechos) OR (el derecho))~".
• Adding a wildcard symbol may retrieve word variants: ((sanciones administrativa) or (sanciones administrativas)) jogos economicos ((el derechos) OR (el derecho))*.
