Perhaps you should try some spelling variations:
funcion administrativa » gestion administrativa, sanciones administrativas
administrativos del » administrativos de, administrativo de
administrativa del » administrativa de, administrativa en, administrativa y
censo economico » ciclo economico, penal economico, tecnico economico
costo economico » costos economicos, corte economico, cost economics
caso economico » campo economico, cambio economico, pasivo 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 (censo economico))) OR (costo economico)) del derecho\") or (\"funcion ((administrativa del) OR (administrativos del)) economico del derecho\"))".
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((\\"funcion administrativa ((((caso economico) OR (censo economico))) or (costo economico)) del derecho\\") or (\\"funcion ((administrativa del) or (administrativos del)) economico del derecho\\"))\"".
• Removing quotes may allow a broader search: (( funcion administrativa ((((caso economico) OR (censo economico))) or (costo economico)) del derecho ) or ( funcion ((administrativa del) or (administrativos del)) economico del derecho )).
