Perhaps you should try some spelling variations:
"communicate diseases" » "complicated diseases", "communicate messages", "community disease"
"communicate discover" » "community discovery", "communications over", "communicate listen"
"communicate disabled" » "communicate listen", "communicate defined", "communicate deliverables"
"communicated disease" » "complicated diseases", "communicate state"
"communicated vision" » "community vision"

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 discover"))) OR ((("communicate disabled") 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 discover\"))) or (((\"communicate disabled\") or (((\"communicated disease\") or (\"communicated vision\"))))))) or (((\"communicable diseases\") or (\"communicable disease\"))))".
• Removing quotes may allow a broader search: (((((( communicate diseases ) OR ( communicate discover ))) or ((( communicate disabled ) or ((( communicated disease ) or ( communicated vision ))))))) or ((( communicable diseases ) or ( communicable disease )))).
• Adding a wildcard symbol may retrieve word variants: (((((("communicate diseases") OR ("communicate discover"))) or ((("communicate disabled") or ((("communicated disease") or ("communicated vision"))))))) or ((("communicable diseases") or ("communicable disease"))))*.
