• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach hoi thu hien ((nhi cua) OR (nghi cua)) ets : nhung ((bo honc) OR (bo hon)) vi đai~.
• Adding a wildcard symbol may retrieve word variants: tu sach hoi thu hien ((nhi cua) or (nghi cua)) ets : nhung ((bo honc) or (bo hon)) vi đai*.
