Perhaps you should try some spelling variations:
"communicated visions" » "communicated vision", "communication visions", "communicate visual", "communicated vissons", "communicated visins"
"communicated disease" » "complicated diseases", "communicate state", "communicated vision"
"communicat ions" » "communicat sons", "communicat ion", "communicat ins"

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