• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky ((dang xa) or (van xay)) hoi. hieu van cam cuc ban hanh ((vai cua) OR (hai cua)) te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky ((dang xa) OR (van xay)) hoi. hieu van cam cuc ban hanh ((vai cua) OR (hai cua)) te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky ((dang xa) or (van xay)) hoi. hieu van cam cuc ban hanh ((vai cua) OR (hai cua)) te*".
