Perhaps you should try some spelling variations:
communication conversation » communication information, communication cohesion, communication communication
mixed precision » fixed precision, based precision, model precision
dies precision » de precision, fixed precision, reese precision
data banks » data bank, data bases
data line » data lines, data link, data life

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 conversation ((mixed precision) OR (dies precision)) ((data line) OR (data banks))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "communication conversation ((mixed precision) OR (dies precision)) ((data line) or (data banks))~".
• Adding a wildcard symbol may retrieve word variants: communication conversation ((mixed precision) OR (dies precision)) ((data line) or (data banks))*.
