• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ty ((hang ho) OR (hang cho)) hai. hieu ve cac ((vuc van) or (duc va)) nhanh thai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty ((hang ho) OR (hang cho)) hai. hieu ve cac ((vuc van) OR (duc va)) nhanh thai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty ((hang ho) OR (hang cho)) hai. hieu ve cac ((vuc van) or (duc va)) nhanh thai cua tre*".
