Perhaps you should try some spelling variations:
"communicated disease" » "complicated diseases", "communicated vision"
"communication style" » "communication styles", "communication studies", "communication scheme"
"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 ((((("communicated disease") OR ("communicable disease"))) OR ((("communicate state") OR ("communication style")))))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"communicable diseases\") or (((((\"communicated disease\") OR (\"communicable disease\"))) or (((\"communicate state\") or (\"communication style\"))))))".
• Removing quotes may allow a broader search: (( communicable diseases ) or ((((( communicated disease ) OR ( communicable disease ))) or ((( communicate state ) or ( communication style )))))).
• Adding a wildcard symbol may retrieve word variants: (("communicable diseases") or ((((("communicated disease") OR ("communicable disease"))) or ((("communicate state") or ("communication style"))))))*.
