• If you are trying to use Boolean operators, they must be ALL CAPS: wing tan yang lun yu ((song min) OR (anh minh)) ((tong shui) OR (gong hui)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wing tan yang lun yu ((song min) or (anh minh)) ((tong shui) OR (gong hui)) ;~".
• Adding a wildcard symbol may retrieve word variants: wing tan yang lun yu ((song min) or (anh minh)) ((tong shui) OR (gong hui)) ;*.
