• Performing a fuzzy search may retrieve terms with similar spellings: tu ((((sach ty) OR (xach tay))) or (sach y)) lang xa hoi. hieu ve cau luc ngan hang vi cau tren~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((((sach ty) OR (xach tay))) OR (sach y)) lang xa hoi. hieu ve cau luc ngan hang vi cau tren*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((((sach ty) OR (xach tay))) or (sach y)) lang xa hoi. hieu ve cau luc ngan hang vi cau tren*".
