• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - hanh ((hinh cua) OR (((chinh sua) OR (chinh su)))) nhung cuong tap toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - hanh ((hinh cua) or (((chinh sua) OR (chinh su)))) nhung cuong tap toan cao~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - hanh ((hinh cua) or (((chinh sua) OR (chinh su)))) nhung cuong tap toan cao*.
