Perhaps you should try some spelling variations:
"communicated diseases" » "communicable diseases", "communicate disabled", "communicate discover", "communicable diseasess", "communicated visions"
"communicable disease" » "communicable diseases"
"communicated disease" » "communicable diseases", "communicated vision"
"complicated diseases" » "complicated cases", "complex diseases", "mediated diseases"
"communicate state" » "communicate strategy", "communicating state", "communication state"

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