Perhaps you should try some spelling variations:
"communicate diseases" » "communicated disease", "complicated diseases", "communicate discover"
"communicate disabled" » "communicate discover", "communicate listen", "communicated disease"
"communicate state" » "communicate strategy", "communicating state", "communication state"

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: (((("communicate diseases") OR ((("communicate disabled") OR ("communicate state"))))) OR ((("communicable diseases") OR ("communicable disease")))).
• Removing quotes may allow a broader search: (((( communicate diseases ) or ((( communicate disabled ) or ( communicate state ))))) or ((( communicable diseases ) or ( communicable disease )))).
• Adding a wildcard symbol may retrieve word variants: (((("communicate diseases") or ((("communicate disabled") or ("communicate state"))))) or ((("communicable diseases") or ("communicable disease"))))*.
