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