• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky ((lang mai) OR (lang dai)) khoi. hieu ve cham xuc van hanh tai ((cuu tre) or (cau treo))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky ((lang mai) OR (lang dai)) khoi. hieu ve cham xuc van hanh tai ((cuu tre) OR (cau treo)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky ((lang mai) OR (lang dai)) khoi. hieu ve cham xuc van hanh tai ((cuu tre) or (cau treo))".
• Adding a wildcard symbol may retrieve word variants: te sach ky ((lang mai) OR (lang dai)) khoi. hieu ve cham xuc van hanh tai ((cuu tre) or (cau treo))*.
