• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ky nang ((((x hoi) OR (x ho))) or (xa hoi)). hieu qua cham qua ban anh d cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ky nang ((((x hoi) OR (x ho))) OR (xa hoi)). hieu qua cham qua ban anh d cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ky nang ((((x hoi) OR (x ho))) or (xa hoi)). hieu qua cham qua ban anh d cua tre*".
