• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - thanh trung cap ((hoang cong) OR (hoang trong)) ((ban pho) OR (ban nha)) cau~.
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - thanh trung cap ((hoang cong) or (hoang trong)) ((ban pho) or (ban nha)) cau*.
