• If you are trying to use Boolean operators, they must be ALL CAPS: so sach thu ((tang van) OR (dang van)) hoi. lieu va cham ((xuc va) OR (duc va)) hanh vai cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach thu ((tang van) OR (dang van)) hoi. lieu va cham ((xuc va) or (duc va)) hanh vai cua te*".
