• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky dang xa hoi. hieu vu cham ((hat van) OR (hoat van)) thanh ((sang cua) or (song cua)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky dang xa hoi. hieu vu cham ((hat van) OR (hoat van)) thanh ((sang cua) OR (song cua)) tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky dang xa hoi. hieu vu cham ((hat van) OR (hoat van)) thanh ((sang cua) or (song cua)) tre*".
