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