• Performing a fuzzy search may retrieve terms with similar spellings: vu san ky nang x hoi. hieu ve cam tuc ((va dinh) OR (va kinh)) di ((cau treo) or (cu tren))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu san ky nang x hoi. hieu ve cam tuc ((va dinh) OR (va kinh)) di ((cau treo) OR (cu tren)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu san ky nang x hoi. hieu ve cam tuc ((va dinh) OR (va kinh)) di ((cau treo) or (cu tren))".
• Adding a wildcard symbol may retrieve word variants: vu san ky nang x hoi. hieu ve cam tuc ((va dinh) OR (va kinh)) di ((cau treo) or (cu tren))*.
