Perhaps you should try some spelling variations:
"communicate diseases" » "communicated disease", "complicated diseases", "communicate discover"
"communicate disabled" » "communicate discover", "communicated disease", "communicate defined"
"communicate listen" » "communication listen", "communicate like", "communicate better"

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