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