• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach nha my giai ((con hong) OR (cong thong)) tin ) OR ( su sach cha me giai co trong tin ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu sach nha my giai ((con hong) OR (cong thong)) tin ) or ( su sach cha me giai co trong tin ))*".
