methods diffusion » networks diffusion, methods decision
cohesion methods » conversion methods, corrosion methods, adhesion method
scale spaces » scale space, sample spaces
whose spaces » phase spaces, shape spaces, whose race
tuple spaces » tuple space, type spaces, triple space

• If you are trying to use Boolean operators, they must be ALL CAPS: communication cohesion methods diffusion ((scale spaces) OR (((whose spaces) OR (tuple spaces)))).
• Adding a wildcard symbol may retrieve word variants: communication cohesion methods diffusion ((scale spaces) or (((whose spaces) or (tuple spaces))))*.
