• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty xang xa hoi. lieu va nam ((((duc va) OR (loc va))) OR (truc va)) vanh dai cua tre.
• Adding a wildcard symbol may retrieve word variants: tu sach ty xang xa hoi. lieu va nam ((((duc va) or (loc va))) or (truc va)) vanh dai cua tre*.
