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