• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ky) OR (sac ky)) nang ma hoi. thieu ((vien da) OR (vien dai)) xuc va danh 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 da) OR (vien dai)) xuc va danh va cua triet*".
