• Performing a fuzzy search may retrieve terms with similar spellings: vu san ky nang xa hoi. ((hieu viec) OR (sieu viet)) ((cac luc) or (cau luc)) va hanh vai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu san ky nang xa hoi. ((hieu viec) OR (sieu viet)) ((cac luc) OR (cau luc)) va hanh vai cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu san ky nang xa hoi. ((hieu viec) OR (sieu viet)) ((cac luc) or (cau luc)) va hanh vai cua te*".
