• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ky) OR (sach y)) sang mai khoi. ((hieu ve) OR (hieu va)) cam luc va thanh van cua vat.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) OR (sach y)) sang mai khoi. ((hieu ve) or (hieu va)) cam luc va thanh van cua vat".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ky) OR (sach y)) sang mai khoi. ((hieu ve) or (hieu va)) cam luc va thanh van cua vat*.
