• Performing a fuzzy search may retrieve terms with similar spellings: toc sac ky nang ma hoi. thi van ((cac xuc) or (cam xuc)) va hanh lam ((cua viet) OR (ca viet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc sac ky nang ma hoi. thi van ((cac xuc) OR (cam xuc)) va hanh lam ((cua viet) OR (ca viet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sac ky nang ma hoi. thi van ((cac xuc) or (cam xuc)) va hanh lam ((cua viet) OR (ca viet))".
