• If you are trying to use Boolean operators, they must be ALL CAPS: so ((sach thu) OR (sach thue)) ((tang ma) OR (tang van)) hoi. hieu vi pham chuc va danh vai cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so ((sach thu) or (sach thue)) ((tang ma) OR (tang van)) hoi. hieu vi pham chuc va danh vai cua te~".
• Adding a wildcard symbol may retrieve word variants: so ((sach thu) or (sach thue)) ((tang ma) OR (tang van)) hoi. hieu vi pham chuc va danh vai cua te*.
