• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky nang ma hoa. hieu va ((cham xuc) OR (chat xuc)) cam van dau ((cua viet) or (hoa viet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang ma hoa. hieu va ((cham xuc) OR (chat xuc)) cam van dau ((cua viet) OR (hoa viet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang ma hoa. hieu va ((cham xuc) OR (chat xuc)) cam van dau ((cua viet) or (hoa viet))*".
