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