• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo tieu) or (hoc thieu)) xanh - hanh tang cua thong ((cong tan) OR (cong tac)) tran chau~".
• Adding a wildcard symbol may retrieve word variants: ((theo tieu) or (hoc thieu)) xanh - hanh tang cua thong ((cong tan) OR (cong tac)) tran chau*.
