• Performing a fuzzy search may retrieve terms with similar spellings: thu sac ky nang ((cao hoi) OR (co hoi)). hieu vu cham soc va hanh ((tai cua) or (thai cua)) te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sac ky nang ((cao hoi) OR (co hoi)). hieu vu cham soc va hanh ((tai cua) OR (thai cua)) te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sac ky nang ((cao hoi) OR (co hoi)). hieu vu cham soc va hanh ((tai cua) or (thai cua)) te*".
