• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty ((xang xa) OR (ang xa)) hoi. hieu van bac nuoc va ((tinh va) OR (trinh van)) cua tu~.
• Adding a wildcard symbol may retrieve word variants: tu sach ty ((xang xa) or (ang xa)) hoi. hieu van bac nuoc va ((tinh va) or (trinh van)) cua tu*.
