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