• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach v ((nang ma) OR (sang ma)) hoi. hieu van bao luc va thanh ((lam cua) OR (luan chat)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach v ((nang ma) OR (sang ma)) hoi. hieu van bao luc va thanh ((lam cua) or (luan chat)) triet".
