• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((ky sang) OR (ky nang)) xa hoi. thi van cam ((xuc va) OR (tuc va)) hang va cuu tre.
• Adding a wildcard symbol may retrieve word variants: tu sach ((ky sang) or (ky nang)) xa hoi. thi van cam ((xuc va) or (tuc va)) hang va cuu tre*.
