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