• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu sach - hanh ((((cdinh cua) OR (sinh cua))) OR (dinh cua)) nhung cong tac tren chau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu sach - hanh ((((cdinh cua) OR (sinh cua))) or (dinh cua)) nhung cong tac tren chau~".
• Adding a wildcard symbol may retrieve word variants: theo chieu sach - hanh ((((cdinh cua) OR (sinh cua))) or (dinh cua)) nhung cong tac tren chau*.
