• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (chieu sach)) - hanh tran va hang cong ((san than) OR (sang than)) cao*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (chieu sach)) - hanh tran va hang cong ((san than) OR (sang than)) cao*".
