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