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"
"communicated vision" » "community vision"
"communicate listen" » "communication listen", "communicate like", "communicate better"

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 ((("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 (((\"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 ((( 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 ((("communicable diseases") or ("communicable disease"))))*.
