• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((thieu xanh) OR (chieu sach)) - hanh ((trang cua) OR (tang cua)) nhung cong van van ban~.
• Adding a wildcard symbol may retrieve word variants: hoc ((thieu xanh) or (chieu sach)) - hanh ((trang cua) or (tang cua)) nhung cong van van ban*.
