Perhaps you should try some spelling variations:
"communicate diseases" » "communicate discover", "communicate messages", "community disease"
"communicate disabled" » "communicate discover", "communicate listen", "communicate defined"
"communicated disease" » "communicate state"
"complicated diseases" » "complicated cases", "complex diseases", "mediated diseases"
"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 disabled") OR ((((("communicated disease") OR ("complicated diseases"))) 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 (((((\"communicated disease\") 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 ((((( communicated disease ) 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 ((((("communicated disease") OR ("complicated diseases"))) or ("communicated vision"))))))) or ((("communicable diseases") or ("communicable disease"))))*.
