• The words AND, OR and NOT may confuse the search; try adding quotes: "doc ((hieu sach) or (hieu cach)) - hanh trinh ((ban cung) OR (bai cung)) phong anh tuan cao~".
• Adding a wildcard symbol may retrieve word variants: doc ((hieu sach) or (hieu cach)) - hanh trinh ((ban cung) OR (bai cung)) phong anh tuan cao*.
