• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu sang - ((van doanh) OR (van dong)) cua thong cong ((dan ca) OR (van tuan)) cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu sang - ((van doanh) OR (van dong)) cua thong cong ((dan ca) or (van tuan)) cau*".
