• If you are trying to use Boolean operators, they must be ALL CAPS: liang tan yong xi liu ((gang minh) OR (sang minh)) ((tong shui) OR (zhong zhi)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "liang tan yong xi liu ((gang minh) OR (sang minh)) ((tong shui) or (zhong zhi)) ;~".
• Adding a wildcard symbol may retrieve word variants: liang tan yong xi liu ((gang minh) OR (sang minh)) ((tong shui) or (zhong zhi)) ;*.
