Perhaps you should try some spelling variations:
"chan denis robinson" » "chan lewis robinson", "chan daniel robinson", "chan defoes robinson", "can denis robinson", "chains denis robinson", "chan kennis robinson"
"can deny johnson" » "can henry johnson", "can penny johnson", "can ben johnson"
"chan denise robson" » "can denis robson", "coghlan denise robson", "tsang denise robson", "can denise robson", "chains denise robson", "chan kennise 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 ("chan denis robinson")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"can deny johnson\") or (((\"chan denise robson\") OR (\"chan denis robinson\"))))".
• Removing quotes may allow a broader search: (( can deny johnson ) or ((( chan denise robson ) OR ( chan denis robinson )))).
• Adding a wildcard symbol may retrieve word variants: (("can deny johnson") or ((("chan denise robson") OR ("chan denis robinson"))))*.
