• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (doi chi)) tinh - thanh tung ((chap tuong) OR (chat luong)) duong ba thuan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (doi chi)) tinh - thanh tung ((chap tuong) OR (chat luong)) duong ba thuan cau".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (doi chi)) tinh - thanh tung ((chap tuong) OR (chat luong)) duong ba thuan cau*.
