• If you are trying to use Boolean operators, they must be ALL CAPS: (( thu sach ((tranh tri) OR (trang tri)) ) OR ((( tu sach luyen tri ) OR ( tu tang luan tri ))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( thu sach ((tranh tri) OR (trang tri)) ) or ((( tu sach luyen tri ) or ( tu tang luan tri ))))*".
