Perhaps you should try some spelling variations:
"communicate disabled" » "communicate discover", "communicate listen", "communicate deliverables"
"communicable disease" » "communicable diseases"
"communicated disease" » "communicable diseases", "complicated diseases", "communicate state"
"communicate defined" » "community defined", "communication defines", "communication define"

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