• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - ((thanh truong) OR (thanh tung)) cua thong cong ((dan gian) OR (dan giang)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - ((thanh truong) OR (thanh tung)) cua thong cong ((dan gian) or (dan giang)) cau~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - ((thanh truong) OR (thanh tung)) cua thong cong ((dan gian) or (dan giang)) cau*.
