Perhaps you should try some spelling variations:
communication channel » communication channels, communication case, communication challenges
base precision » based precision, biased precision, laser precision
data resolving » dates resolving, data removing, data solving
data evolving » data involving, data solving, dogma evolving
channel base » channel based, channels based, channel basin
data making » data mapping, data mining, data working

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 channel base precision ((((data evolving) OR (data resolving))) OR (data making))~.
• Adding a wildcard symbol may retrieve word variants: communication channel base precision ((((data evolving) or (data resolving))) or (data making))*.
