Perhaps you should try some spelling variations:
"communicated disease" » "communicable disease", "communicate state"
"complicated diseases" » "complicated cases", "complex diseases", "mediated diseases"
"communicated vision" » "community vision"
"communicable diseases" » "communicate diseases"

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 disease") OR ("communicated vision"))) OR ("complicated diseases")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"communicable diseases\") or (((((\"communicated disease\") OR (\"communicated vision\"))) or (\"complicated diseases\"))))".
• Removing quotes may allow a broader search: (( communicable diseases ) or ((((( communicated disease ) OR ( communicated vision ))) or ( complicated diseases )))).
• Adding a wildcard symbol may retrieve word variants: (("communicable diseases") or ((((("communicated disease") OR ("communicated vision"))) or ("complicated diseases"))))*.
