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