• Performing a fuzzy search may retrieve terms with similar spellings: thuat sach ty lang xa hoi. hieu ve cam tuc xa thanh hai ((cau tren) or (((cua tre) OR (cuu tre))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat sach ty lang xa hoi. hieu ve cam tuc xa thanh hai ((cau tren) OR (((cua tre) OR (cuu tre))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat sach ty lang xa hoi. hieu ve cam tuc xa thanh hai ((cau tren) or (((cua tre) OR (cuu tre))))*".
