• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (su sach)) ky nang x hoi. hieu ve cac xuc va dan ((vi la) OR (vi ha)) tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (su sach)) ky nang x hoi. hieu ve cac xuc va dan ((vi la) OR (vi ha)) tren".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (su sach)) ky nang x hoi. hieu ve cac xuc va dan ((vi la) OR (vi ha)) tren*.
