• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (te sach)) thu tang van hoc. ((hieu van) OR (lieu va)) cau tuc va dan vi cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (te sach)) thu tang van hoc. ((hieu van) or (lieu va)) cau tuc va dan vi cuu tre*".
