• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky ((lang xa) OR (lang ha)) hoi. lieu va ((chat xuc) OR (cam xuc)) va vanh dai cuu tre.
• Adding a wildcard symbol may retrieve word variants: tu sach ky ((lang xa) or (lang ha)) hoi. lieu va ((chat xuc) or (cam xuc)) va vanh dai cuu tre*.
