• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (chieu sach)) - hanh trong quang ((dung huong) OR (dung phuong)) ban thanh cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) OR (chieu sach)) - hanh trong quang ((dung huong) or (dung phuong)) ban thanh cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) OR (chieu sach)) - hanh trong quang ((dung huong) or (dung phuong)) ban thanh cau*.
