Perhaps you should try some spelling variations:
"communicate diseases" » "communicated disease", "communicate discover", "communicate messages"
"communicate disabled" » "communicate discover", "communicate listen", "communicated disease"
"complicated diseases" » "complicated cases", "complex diseases", "mediated diseases"
"communicated vision" » "community vision", "communicated disease"

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