• If you are trying to use Boolean operators, they must be ALL CAPS: ((doc hieu) OR (hoc hien)) xanh - hanh trang cua thong cong ((thanh toan) OR (dan than)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doc hieu) OR (hoc hien)) xanh - hanh trang cua thong cong ((thanh toan) or (dan than)) cau~".
• Adding a wildcard symbol may retrieve word variants: ((doc hieu) OR (hoc hien)) xanh - hanh trang cua thong cong ((thanh toan) or (dan than)) cau*.
