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