• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu sach) OR (vu khach)) ty xang xa hoi. lieu va nam ((xuc ban) OR (can ban)) ban vi cuu tre.
• Adding a wildcard symbol may retrieve word variants: ((thu sach) or (vu khach)) ty xang xa hoi. lieu va nam ((xuc ban) or (can ban)) ban vi cuu tre*.
