• Performing a fuzzy search may retrieve terms with similar spellings: toc sach ((y lang) or (o lang)) van hoa. hieu ve cham tuc van ((anh di) OR (xanh di)) cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach ((y lang) OR (o lang)) van hoa. hieu ve cham tuc van ((anh di) OR (xanh di)) cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach ((y lang) or (o lang)) van hoa. hieu ve cham tuc van ((anh di) OR (xanh di)) cua te*".
