• If you are trying to use Boolean operators, they must be ALL CAPS: luong thanh thanh china all ((((yang xi) OR (yang yi))) OR (yang july)) (wang OR wing) hua ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "luong thanh thanh china all ((((yang xi) or (yang yi))) or (yang july)) (wang OR wing) hua ;~".
• Adding a wildcard symbol may retrieve word variants: luong thanh thanh china all ((((yang xi) or (yang yi))) or (yang july)) (wang OR wing) hua ;*.
