• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ly nang x hoi. ((lieu va) OR (((thien van) OR (thi van)))) nam thu va hanh vi cuu tre.
• Adding a wildcard symbol may retrieve word variants: su sach ly nang x hoi. ((lieu va) or (((thien van) or (thi van)))) nam thu va hanh vi cuu tre*.
