• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((v nang) OR (cam nang)) xa hoi. hieu va hau luu van ((hanh de) OR (hanh ve)) cua tre.
• Adding a wildcard symbol may retrieve word variants: te sach ((v nang) or (cam nang)) xa hoi. hieu va hau luu van ((hanh de) or (hanh ve)) cua tre*.
