Perhaps you should try some spelling variations:
communication cost » communication costs, communication costa, communications costs
driven development » urban development
put communication » post communication, et communication, get communication
relation 5.5 » relations 5.5, relation 4.5, relation 5.3
cost driven » cost drivers, test driven
5.5 role » 3.5 role
role put » role pt, role pour, role du
case can » case case
case c » case 1, case 2, case 3

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: "technology _ relation 5.5 role put communication cost driven development ((case can) OR (case c)).~".
• Adding a wildcard symbol may retrieve word variants: technology _ relation 5.5 role put communication cost driven development ((case can) OR (case c)).*.
