• If you are trying to use Boolean operators, they must be ALL CAPS: dong tin tan china's ((road loading) OR (head loading)) ((jin song) OR (john song)) shin ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong tin tan china's ((road loading) OR (head loading)) ((jin song) or (john song)) shin ;~".
• Adding a wildcard symbol may retrieve word variants: dong tin tan china's ((road loading) OR (head loading)) ((jin song) or (john song)) shin ;*.
