communication collections » communication applications, communication cohesion, communication foundations
collections metric » collections generic, collections music, collections generics
design basic » designs basic, design basis, desi6n basics
design based » design case

• If you are trying to use Boolean operators, they must be ALL CAPS: communication collections metric ((((design basic) OR (design basics))) OR (design based)) linear.
• Adding a wildcard symbol may retrieve word variants: communication collections metric ((((design basic) or (design basics))) or (design based)) linear*.
