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