• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky tang ma hoa. hieu van cham ((xuc ban) or (nuoc luan)) hanh vi ((cua tre) OR (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky tang ma hoa. hieu van cham ((xuc ban) OR (nuoc luan)) hanh vi ((cua tre) OR (cua te))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky tang ma hoa. hieu van cham ((xuc ban) or (nuoc luan)) hanh vi ((cua tre) OR (cua te))*".
