• If you are trying to use Boolean operators, they must be ALL CAPS: doi chi xanh - thanh tung ((cua thong) OR (cua phuong)) thong tan ((than cau) OR (phan cau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chi xanh - thanh tung ((cua thong) or (cua phuong)) thong tan ((than cau) OR (phan cau))~".
• Adding a wildcard symbol may retrieve word variants: doi chi xanh - thanh tung ((cua thong) or (cua phuong)) thong tan ((than cau) OR (phan cau))*.
