Perhaps you should try some spelling variations:
"communicate diseases" » "communicable disease", "complicated diseases", "communicate disabled"
"communicated disease" » "communicable disease", "complicated diseases", "communicated vision"
"communicate strategy" » "communicative strategy", "communication strategy", "community strategy"
"communicate state" » "communicating state", "communication state", "communicate make"

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