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