• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu sang - ((doanh doanh) OR (((hanh doanh) OR (nhung doanh)))) van nang nong dan chan cau~.
• Adding a wildcard symbol may retrieve word variants: doi chieu sang - ((doanh doanh) or (((hanh doanh) or (nhung doanh)))) van nang nong dan chan cau*.
