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