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