• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ty) OR (sach y)) ((sang ma) OR (lang van)) hoi. hieu ve cac duc van anh vi cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ty) OR (sach y)) ((sang ma) or (lang van)) hoi. hieu ve cac duc van anh vi cua triet*".
