Perhaps you should try some spelling variations:
comunicaci » comunicar, comunica, comunicativa
comunicacio » comunicaro, comunicao, comunicativao
comunicacion » comunicaron, comunicaon, comunicativaon
comunicado » comunicador, comunicacao, comunidad
comunicando » comunicador, comunicativo, comunicantes
comunicacon » comunicador, comunicaciones, comunicacional
communicating » communicative, comunicativa, comunicativo
communications » comunicaciones, comunicativas

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: ((comunicaci OR (comunicacio OR ((comunicado OR comunicando) OR comunicacon))) OR (comunicacion OR ((communicating OR communications) OR communication))){acute}o.~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((comunicaci or (comunicacio or ((comunicado OR comunicando) or comunicacon))) or (comunicacion or ((communicating or communications) or communication))){acute}o.~".
• Adding a wildcard symbol may retrieve word variants: ((comunicaci or (comunicacio or ((comunicado OR comunicando) or comunicacon))) or (comunicacion or ((communicating or communications) or communication))){acute}o.*.
