Perhaps you should try some spelling variations:
communication conversation » communication information, communication cohesion, communication communication
fixed precision » mixed precision, based precision, finite precision
dies precision » de precision, mixed precision, reese precision
data lines » data links, date lines, data linear
data line » data link, data life, data mine

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