• Performing a fuzzy search may retrieve terms with similar spellings: ((hoc sach) or (te sach)) ky nang ma hoa. hieu va cam xuc va ((danh vinh) OR (anh vinh)) cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc sach) OR (te sach)) ky nang ma hoa. hieu va cam xuc va ((danh vinh) OR (anh vinh)) cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc sach) or (te sach)) ky nang ma hoa. hieu va cam xuc va ((danh vinh) OR (anh vinh)) cuu tre".
• Adding a wildcard symbol may retrieve word variants: ((hoc sach) or (te sach)) ky nang ma hoa. hieu va cam xuc va ((danh vinh) OR (anh vinh)) cuu tre*.
