Perhaps you should try some spelling variations:
communication conversation » communication information, communication cohesion, communication communication
conversation dies » conversation games, conversation rules, conversation medium
dies precision » de precision, fixed precision, mixed 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.

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