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