• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo chu) OR (cho chu)) van - hanh ((tang luan) OR (hang cua)) nhung cong van tan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chu) OR (cho chu)) van - hanh ((tang luan) or (hang cua)) nhung cong van tan ban~".
• Adding a wildcard symbol may retrieve word variants: ((theo chu) OR (cho chu)) van - hanh ((tang luan) or (hang cua)) nhung cong van tan ban*.
