Perhaps you should try some spelling variations:
operator » operatoria, operar, operate
operacion » cooperacion, operaciones
operador » operadores, emperador
operaria » operario, operatoria, operativa
operational » operacional, operations, operacionales, cooperational, operativosal, operativoal
operation » cooperation, operativos, operativo

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "UGC (cinema (((operator OR operacion) OR operador) OR ((operaria OR operational) OR operation)))~".
• Adding a wildcard symbol may retrieve word variants: UGC (cinema (((operator OR operacion) OR operador) OR ((operaria OR operational) OR operation)))*.
