• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) OR (te sach)) ky nang co hoi. hieu ve cham xuc van hanh ((vi cuu) or (vi luu)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (te sach)) ky nang co hoi. hieu ve cham xuc van hanh ((vi cuu) OR (vi luu)) tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (te sach)) ky nang co hoi. hieu ve cham xuc van hanh ((vi cuu) or (vi luu)) tre*".
