Perhaps you should try some spelling variations:
communication costs » communication systems, communication efforts, communication skills
cash communication » mass communication, mass communications, risk communication
information gaps » information gap, information flows, information needs
code development » model development, care development, trade development
development a » development _, development bank, development banks

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: "technologies _ information gaps (does OR des) cash communication costs code development a afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies _ information gaps (does OR des) cash communication costs code development a afrique.*.
