Perhaps you should try some spelling variations:
"communicated diseases" » "complicated diseases", "communicable disease", "communicate disabled", "communicable diseases", "complicated diseasess", "communicate states"
"communicate strategy" » "communicative strategy", "communication strategy", "community strategy"
"communicated disease" » "communicable disease", "complicated diseases", "communicate 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 diseases") OR ("communicate strategy"))) OR ("communicated disease")))).
• Removing quotes may allow a broader search: (( communicable diseases ) or ((((( communicated diseases ) or ( communicate strategy ))) or ( communicated disease )))).
• Adding a wildcard symbol may retrieve word variants: (("communicable diseases") or ((((("communicated diseases") or ("communicate strategy"))) or ("communicated disease"))))*.
