• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ha) OR (sach han)) nang x hoi. ((thien van) OR (thi van)) cau xuc va hang doi cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ha) OR (sach han)) nang x hoi. ((thien van) or (thi van)) cau xuc va hang doi cua triet*".
