• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu tang - hanh chinh ((sua hang) OR (sua nang)) ((nong dan) OR (cong dan)) toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu tang - hanh chinh ((sua hang) OR (sua nang)) ((nong dan) or (cong dan)) toan ban~".
• Adding a wildcard symbol may retrieve word variants: ho chieu tang - hanh chinh ((sua hang) OR (sua nang)) ((nong dan) or (cong dan)) toan ban*.
