Perhaps you should try some spelling variations:
"communicated diseases" » "complicated diseases", "communicable disease", "communicate discover", "communicable diseases", "complicated diseasess", "communicated visions"
"communicate disabled" » "communicate discover", "communicate listen", "communicate defined"
"communicated disease" » "communicable disease", "complicated diseases", "communicated vision"
"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 diseases") OR ((((("communicated diseases") OR ("communicate disabled"))) OR ((("communicated disease") OR ("communicate state")))))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"communicable diseases\") or (((((\"communicated diseases\") or (\"communicate disabled\"))) or (((\"communicated disease\") OR (\"communicate state\"))))))".
• Removing quotes may allow a broader search: (( communicable diseases ) or ((((( communicated diseases ) or ( communicate disabled ))) or ((( communicated disease ) OR ( communicate state )))))).
• Adding a wildcard symbol may retrieve word variants: (("communicable diseases") or ((((("communicated diseases") or ("communicate disabled"))) or ((("communicated disease") OR ("communicate state"))))))*.
