• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sach) OR (toc sach)) _ dang van hoi. hieu va cam luc gia ((hanh vi) OR (thanh va)) cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) OR (toc sach)) _ dang van hoi. hieu va cam luc gia ((hanh vi) or (thanh va)) cuu tre*".
