• Performing a fuzzy search may retrieve terms with similar spellings: ho chieu xanh - ((((hanh trang) OR (thanh trung))) or (hanh trinh)) hua khong huong dan chan ban~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - ((((hanh trang) OR (thanh trung))) OR (hanh trinh)) hua khong huong dan chan ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - ((((hanh trang) OR (thanh trung))) or (hanh trinh)) hua khong huong dan chan ban".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - ((((hanh trang) OR (thanh trung))) or (hanh trinh)) hua khong huong dan chan ban*.
