• Performing a fuzzy search may retrieve terms with similar spellings: te ((sach ty) or (sach tu)) nang xa hoi. nhieu viec cac lo van danh va ((cuu tre) OR (cau treo))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ty) OR (sach tu)) nang xa hoi. nhieu viec cac lo van danh va ((cuu tre) OR (cau treo))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ty) or (sach tu)) nang xa hoi. nhieu viec cac lo van danh va ((cuu tre) OR (cau treo))*".
