• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu sach) OR (vu bach)) ky nang ma hoi. hieu ((ve cham) OR (va cam)) cuc ban hanh di cua vat*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vu sach) OR (vu bach)) ky nang ma hoi. hieu ((ve cham) or (va cam)) cuc ban hanh di cua vat*".
