• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((chieu xanh) OR (chieu sang)) - ((hanh trang) OR (canh tranh)) cua hoang phuong dan toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((chieu xanh) or (chieu sang)) - ((hanh trang) OR (canh tranh)) cua hoang phuong dan toan ban~".
• Adding a wildcard symbol may retrieve word variants: hoc ((chieu xanh) or (chieu sang)) - ((hanh trang) OR (canh tranh)) cua hoang phuong dan toan ban*.
