Perhaps you should try some spelling variations:
communication function » communication functions, communication foundation, communicative functions
based dispersion » wave dispersion, gas dispersion, based discussion
array profiling » array processing, microarray profiling
array using » arrays using
arrays a » arrays _

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