• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu sach) OR (vu bach)) ky dang xay hoi. lieu va cao ((luc van) OR (luoc van)) hanh tai cua tu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vu sach) OR (vu bach)) ky dang xay hoi. lieu va cao ((luc van) or (luoc van)) hanh tai cua tu*".
