• If you are trying to use Boolean operators, they must be ALL CAPS: doc ((hieu sach) OR (hieu cach)) - hanh trinh ban cung ((phong anh) OR (hong anh)) tuan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc ((hieu sach) or (hieu cach)) - hanh trinh ban cung ((phong anh) OR (hong anh)) tuan cao~".
• Adding a wildcard symbol may retrieve word variants: doc ((hieu sach) or (hieu cach)) - hanh trinh ban cung ((phong anh) OR (hong anh)) tuan cao*.
