• If you are trying to use Boolean operators, they must be ALL CAPS: wang yangming yang per test ((kit hong) OR (((kai hong) OR (hai phong)))) song su ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yangming yang per test ((kit hong) or (((kai hong) OR (hai phong)))) song su ;~".
• Adding a wildcard symbol may retrieve word variants: wang yangming yang per test ((kit hong) or (((kai hong) OR (hai phong)))) song su ;*.
