Perhaps you should try some spelling variations:
communication cohesion » communication collections, communication control, communication cost
based dimension » based dispersion, basic dimensions, based extension
cohesion based » conversion based, collision based, corrosion based
array along » arrays long, array arcing, array paving
arrays a » arrays _

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: communication cohesion based dimension ((((array along) or (arrays ang))) or (arrays a))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: communication cohesion based dimension ((((array along) OR (arrays ang))) OR (arrays a)).
• Adding a wildcard symbol may retrieve word variants: communication cohesion based dimension ((((array along) or (arrays ang))) or (arrays a))*.
