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