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