Perhaps you should try some spelling variations:
funcion administrativa » gestion administrativa
administrativos del » administrativos de, administrativo de
administrativa del » administrativa de, administrativa en, administrativa para
administrativa y » administrativa de
costo economico » costos economicos, cost economics, consejo economico
corte economico » aporte economico, lote economico, orden economico
caso economico » censo economico, campo economico, mas economico
economico del » economico de

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