• Performing a fuzzy search may retrieve terms with similar spellings: ho chu tinh - manh ((tran xuan) OR (tran van)) khong cang dan ((chan cau) or (chinh ca))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho chu tinh - manh ((tran xuan) OR (tran van)) khong cang dan ((chan cau) OR (chinh ca)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chu tinh - manh ((tran xuan) OR (tran van)) khong cang dan ((chan cau) or (chinh ca))".
• Adding a wildcard symbol may retrieve word variants: ho chu tinh - manh ((tran xuan) OR (tran van)) khong cang dan ((chan cau) or (chinh ca))*.
