• If you are trying to use Boolean operators, they must be ALL CAPS: doc hieu xanh - hanh trung ((tuan phong) OR (luan phong)) ((cong ban) OR (cong tan)) thanh cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc hieu xanh - hanh trung ((tuan phong) OR (luan phong)) ((cong ban) or (cong tan)) thanh cau~".
• Adding a wildcard symbol may retrieve word variants: doc hieu xanh - hanh trung ((tuan phong) OR (luan phong)) ((cong ban) or (cong tan)) thanh cau*.
