• Performing a fuzzy search may retrieve terms with similar spellings: tu san ky lang xa hoi. hieu va cac luc van anh dao ((cua tre) or (((cuu tre) OR (cau treo))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu san ky lang xa hoi. hieu va cac luc van anh dao ((cua tre) OR (((cuu tre) OR (cau treo))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu san ky lang xa hoi. hieu va cac luc van anh dao ((cua tre) or (((cuu tre) OR (cau treo))))*".
