• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty xang van hoa. hieu ve cam ((luc va) OR (tuc va)) ((hanh di) OR (hanh vi)) cuu tre.
• Adding a wildcard symbol may retrieve word variants: su sach ty xang van hoa. hieu ve cam ((luc va) or (tuc va)) ((hanh di) or (hanh vi)) cuu tre*.
