• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((chieu sach) OR (chieu sang)) - hanh trang thanh ((nhung phuong) OR (nhu phuong)) dan than cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((chieu sach) or (chieu sang)) - hanh trang thanh ((nhung phuong) OR (nhu phuong)) dan than cau".
• Adding a wildcard symbol may retrieve word variants: hoc ((chieu sach) or (chieu sang)) - hanh trang thanh ((nhung phuong) OR (nhu phuong)) dan than cau*.
