Perhaps you should try some spelling variations:
"communication strategy" » "communication strategies", "communication studies"
"communicated disease" » "communicable disease", "complicated diseases", "communicated vision"
"communication state" » "communication style", "communication savante", "communication storage"
"communicating state" » "communicating systems", "communicating climate", "communicating a"
"communicate state" » "communicate strategy", "communicate make", "communicate chapter"

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 ((("communicated disease") OR ((("communicate state") OR ((((("communication state") OR ("communicating state"))) OR ("communication strategy")))))))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"communicable diseases\") or (((\"communicated disease\") or (((\"communicate state\") or (((((\"communication state\") OR (\"communicating state\"))) or (\"communication strategy\"))))))))".
• Removing quotes may allow a broader search: (( communicable diseases ) or ((( communicated disease ) or ((( communicate state ) or ((((( communication state ) OR ( communicating state ))) or ( communication strategy )))))))).
• Adding a wildcard symbol may retrieve word variants: (("communicable diseases") or ((("communicated disease") or ((("communicate state") or ((((("communication state") OR ("communicating state"))) or ("communication strategy"))))))))*.
