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