• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) OR (su sach)) ky nang x ho. thien nhien cac xuc va hanh vai ((cua triet) or (ve triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (su sach)) ky nang x ho. thien nhien cac xuc va hanh vai ((cua triet) OR (ve triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (su sach)) ky nang x ho. thien nhien cac xuc va hanh vai ((cua triet) or (ve triet))".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) OR (su sach)) ky nang x ho. thien nhien cac xuc va hanh vai ((cua triet) or (ve triet))*.
