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