• If you are trying to use Boolean operators, they must be ALL CAPS: te ((((sach ky) OR (sach ty))) OR (sac ky)) nang ma hoi. thieu vien cac vuc van hanh cat cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((((sach ky) OR (sach ty))) or (sac ky)) nang ma hoi. thieu vien cac vuc van hanh cat cua triet*".
