• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (hoc thieu)) xanh - thanh trung tran thong cong tan ((than cau) OR (than cap))~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (hoc thieu)) xanh - thanh trung tran thong cong tan ((than cau) OR (than cap))*.
