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