• Performing a fuzzy search may retrieve terms with similar spellings: te sach thu ((nang cho) or (nang chon)) hoc. hieu ve ((cac vuc) OR (cac vung)) van hanh vi cua cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach thu ((nang cho) OR (nang chon)) hoc. hieu ve ((cac vuc) OR (cac vung)) van hanh vi cua cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach thu ((nang cho) or (nang chon)) hoc. hieu ve ((cac vuc) OR (cac vung)) van hanh vi cua cau*".
