• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - ((thanh tran) OR (thanh tra)) tuan nhung cong ((tan toan) OR (tap toan)) tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - ((thanh tran) or (thanh tra)) tuan nhung cong ((tan toan) OR (tap toan)) tap~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - ((thanh tran) or (thanh tra)) tuan nhung cong ((tan toan) OR (tap toan)) tap*.
