Perhaps you should try some spelling variations:
communication cohesion » communication collections, communication control, communication cost
cohesion using » cohesion during, adhesion using, conversion using
precision data » precision dairy, precision a, precision cut
decision based » decision aid
decision data » decisions data, decision gate, decision aid

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

• Performing a fuzzy search may retrieve terms with similar spellings: communication cohesion using ((((decision data) OR (precision data))) or (decision based)) proving~.
• If you are trying to use Boolean operators, they must be ALL CAPS: communication cohesion using ((((decision data) OR (precision data))) OR (decision based)) proving*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "communication cohesion using ((((decision data) OR (precision data))) or (decision based)) proving*".
