• Performing a fuzzy search may retrieve terms with similar spellings: ho ((((chieu sach) OR (chieu xanh))) or (chiet tach)) - thanh trung cao dong huong dan gian tam~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((((chieu sach) OR (chieu xanh))) OR (chiet tach)) - thanh trung cao dong huong dan gian tam*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((((chieu sach) OR (chieu xanh))) or (chiet tach)) - thanh trung cao dong huong dan gian tam*".
