• If you are trying to use Boolean operators, they must be ALL CAPS: kang han chang kyun ((pin long) OR (pains long)) ((jin chong) OR (tin hong)) yi ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "kang han chang kyun ((pin long) OR (pains long)) ((jin chong) or (tin hong)) yi ;*".
