• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chua xang) OR (chu bang)) - hanh ((tang cua) OR (hang cua)) nhung cong dan toan ban~.
• Adding a wildcard symbol may retrieve word variants: theo ((chua xang) or (chu bang)) - hanh ((tang cua) or (hang cua)) nhung cong dan toan ban*.
