• Performing a fuzzy search may retrieve terms with similar spellings: thu sac ky nang ((cao hoi) OR (co hoi)). hieu vu ((cham lo) or (cam lo)) va hanh tai cua tre~.
• 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 lo) OR (cam lo)) va hanh tai cua tre*.
• 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 lo) or (cam lo)) va hanh tai cua tre*".
