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