• Performing a fuzzy search may retrieve terms with similar spellings: te ((sach ty) or (sach y)) dang ((xay hoi) OR (xa hoi)). hieu ve cam duc ban manh hai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ty) OR (sach y)) dang ((xay hoi) OR (xa hoi)). hieu ve cam duc ban manh hai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ty) or (sach y)) dang ((xay hoi) OR (xa hoi)). hieu ve cam duc ban manh hai cua tre".
