Perhaps you should try some spelling variations:
"communicate diseases" » "complicated diseases", "communicate discover", "communicate messages"
"communicate disabled" » "communicate discover", "communicate defined", "communicate deliverables"
"communicated disease" » "complicated diseases", "communicate state"
"communicate listen" » "communication listen", "communicate like", "communicate better"
"community vision" » "community division", "community provision", "community decision"

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