Perhaps you should try some spelling variations:
communication cohesion » communication collections, communication control, communication cost
mixed precision » fixed precision, based precision, dies precision
cohesion mixed » cohesion based, cohesion model, torsion mixed
data linesar » data linear, data lineage, data links
data linked » data link, data links, data limited
data lines » data links, date lines, data line

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 cohesion mixed precision ((((data lines) OR (data linesar))) OR (data linked))~.
• Adding a wildcard symbol may retrieve word variants: communication cohesion mixed precision ((((data lines) or (data linesar))) or (data linked))*.
