• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((((thieu tinh) OR (trieu tinh))) OR (thien tinh)) - hang doanh cua dong song van hanh mau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((((thieu tinh) OR (trieu tinh))) or (thien tinh)) - hang doanh cua dong song van hanh mau~".
• Adding a wildcard symbol may retrieve word variants: hoc ((((thieu tinh) OR (trieu tinh))) or (thien tinh)) - hang doanh cua dong song van hanh mau*.
