• If you are trying to use Boolean operators, they must be ALL CAPS: doc ((chieu xanh) OR (chieu tinh)) - ((hanh trang) OR (thanh tran)) cua khong thong van luan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc ((chieu xanh) OR (chieu tinh)) - ((hanh trang) or (thanh tran)) cua khong thong van luan ban~".
• Adding a wildcard symbol may retrieve word variants: doc ((chieu xanh) OR (chieu tinh)) - ((hanh trang) or (thanh tran)) cua khong thong van luan ban*.
