• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((trieu tinh) OR (chieu sach)) - ((hanh trang) OR (canh tranh)) va thuong thong mang thang cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((trieu tinh) or (chieu sach)) - ((hanh trang) OR (canh tranh)) va thuong thong mang thang cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((trieu tinh) or (chieu sach)) - ((hanh trang) OR (canh tranh)) va thuong thong mang thang cau*.
