• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (chieu sach)) - thanh trung tuan ((thong huong) OR (thong thong)) dan than cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) OR (chieu sach)) - thanh trung tuan ((thong huong) or (thong thong)) dan than cau".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) OR (chieu sach)) - thanh trung tuan ((thong huong) or (thong thong)) dan than cau*.
