• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((van nang) OR (ly nang)) x hoi. hieu va cam xuc ((va hanh) OR (va thanh)) de cua vat.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((van nang) or (ly nang)) x hoi. hieu va cam xuc ((va hanh) OR (va thanh)) de cua vat".
• Adding a wildcard symbol may retrieve word variants: te sach ((van nang) or (ly nang)) x hoi. hieu va cam xuc ((va hanh) OR (va thanh)) de cua vat*.
