Perhaps you should try some spelling variations:
"chan denise robson" » "chan denis robinson", "coghlan denise robson", "tsang denise robson", "hearn denise robson"
"can deny johnson" » "can henry johnson", "can penny johnson", "can ben johnson"
"can denis robson" » "can denis robinson", "can denis poisson", "can dennis robertson", "jean denis robson", "can dense robson", "n denis robson"

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: (("can deny johnson") OR ((("chan denise robson") OR ("can denis robson")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"can deny johnson\") or (((\"chan denise robson\") OR (\"can denis robson\"))))".
• Removing quotes may allow a broader search: (( can deny johnson ) or ((( chan denise robson ) OR ( can denis robson )))).
• Adding a wildcard symbol may retrieve word variants: (("can deny johnson") or ((("chan denise robson") OR ("can denis robson"))))*.
