Talvez debería tentar con algunhas variantes ortográficas:
communication affecting » communication effective, communication connecting, communication harvesting
communication adhesion » communication cohesion, communication aggression, communication affection
databases optimizing » catalysis optimizing, analysis optimizing, databases mining
all relational » full relational, xml relational, all rational

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: ((communication adhesion) OR (communication affecting)) all relational databases optimizing~.
• Adding a wildcard symbol may retrieve word variants: ((communication adhesion) or (communication affecting)) all relational databases optimizing*.
