• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach y nang x hoi. ((thien van) OR (thi van)) chat truc va ((danh dai) OR (danh di)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach y nang x hoi. ((thien van) OR (thi van)) chat truc va ((danh dai) or (danh di)) cua tre".
• Adding a wildcard symbol may retrieve word variants: thu sach y nang x hoi. ((thien van) OR (thi van)) chat truc va ((danh dai) or (danh di)) cua tre*.
