Perhaps you should try some spelling variations:
"communicated disease" » "communicable disease", "communicate state"
"complicated diseases" » "complicated cases", "mediated diseases", "complicated case"
"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") OR ("complex 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\") OR (\"complex diseases\"))))))".
• Removing quotes may allow a broader search: (( communicable diseases ) or ((((( communicated disease ) or ( communicated vision ))) or ((( complicated diseases ) OR ( complex diseases )))))).
• Adding a wildcard symbol may retrieve word variants: (("communicable diseases") or ((((("communicated disease") or ("communicated vision"))) or ((("complicated diseases") OR ("complex diseases"))))))*.
