• Performing a fuzzy search may retrieve terms with similar spellings: hoc ((chieu sach) or (chau tinh)) - ((hanh tran) OR (hanh trang)) quang hung cong van toan ban~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((chieu sach) OR (chau tinh)) - ((hanh tran) OR (hanh trang)) quang hung cong van toan ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((chieu sach) or (chau tinh)) - ((hanh tran) OR (hanh trang)) quang hung cong van toan ban*".
