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