• Performing a fuzzy search may retrieve terms with similar spellings: toc sach thu hang cho hoc. hieu va ((((cac cuoc) OR (ca cuoc))) or (hoc nuoc)) van hanh vi cua chu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach thu hang cho hoc. hieu va ((((cac cuoc) OR (ca cuoc))) OR (hoc nuoc)) van hanh vi cua chu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach thu hang cho hoc. hieu va ((((cac cuoc) OR (ca cuoc))) or (hoc nuoc)) van hanh vi cua chu*".
