• Performing a fuzzy search may retrieve terms with similar spellings: su sach ty hang xa hoi. hieu ve chat cuu va hanh lai ((dua tren) or (((cuu tre) OR (cau tren))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty hang xa hoi. hieu ve chat cuu va hanh lai ((dua tren) OR (((cuu tre) OR (cau tren))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty hang xa hoi. hieu ve chat cuu va hanh lai ((dua tren) or (((cuu tre) OR (cau tren))))*".
