• Performing a fuzzy search may retrieve terms with similar spellings: ((vay khach) or (vu khanh)) thu ((nang xa) OR (nang x)) hoi. hieu ve nham thuc va hanh lai cua vat~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((vay khach) OR (vu khanh)) thu ((nang xa) OR (nang x)) hoi. hieu ve nham thuc va hanh lai cua vat.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vay khach) or (vu khanh)) thu ((nang xa) OR (nang x)) hoi. hieu ve nham thuc va hanh lai cua vat".
• Adding a wildcard symbol may retrieve word variants: ((vay khach) or (vu khanh)) thu ((nang xa) OR (nang x)) hoi. hieu ve nham thuc va hanh lai cua vat*.
