• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach vu) OR (sach uu)) nang xa hoi. hieu va ((cao xuc) OR (dao duc)) van hanh ve su kien.
• Adding a wildcard symbol may retrieve word variants: te ((sach vu) or (sach uu)) nang xa hoi. hieu va ((cao xuc) or (dao duc)) van hanh ve su kien*.
