• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (bo sach)) y nang ma hoa. hieu ve cac toc tay hanh ((vai cua) OR (hai cua)) triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (bo sach)) y nang ma hoa. hieu ve cac toc tay hanh ((vai cua) OR (hai cua)) triet~".
• Adding a wildcard symbol may retrieve word variants: ((su sach) or (bo sach)) y nang ma hoa. hieu ve cac toc tay hanh ((vai cua) OR (hai cua)) triet*.
