• Performing a fuzzy search may retrieve terms with similar spellings: va ((san ky) OR (van ky)) tang ((mai hoi) or (mai khoi)). hieu vu cham xuc va xanh tai cuc tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: va ((san ky) OR (van ky)) tang ((mai hoi) OR (mai khoi)). hieu vu cham xuc va xanh tai cuc tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "va ((san ky) OR (van ky)) tang ((mai hoi) or (mai khoi)). hieu vu cham xuc va xanh tai cuc tre*".
