Perhaps you should try some spelling variations:
"communicate disabled" » "communicate discover", "communicate listen", "communicate defined"
"communicated disease" » "communicable disease", "complicated diseases", "communicated vision"
"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: (((("communicable diseases") OR ("communicate disabled"))) OR ((("communicated disease") OR ("communicate state")))).
• Removing quotes may allow a broader search: (((( communicable diseases ) or ( communicate disabled ))) or ((( communicated disease ) or ( communicate state )))).
• Adding a wildcard symbol may retrieve word variants: (((("communicable diseases") or ("communicate disabled"))) or ((("communicated disease") or ("communicate state"))))*.
