• Performing a fuzzy search may retrieve terms with similar spellings: te ((lai ky) OR (sai ky)) sang ma hoi. hieu van cam duc ((hoa doanh) or (va danh)) dan cua tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((lai ky) OR (sai ky)) sang ma hoi. hieu van cam duc ((hoa doanh) OR (va danh)) dan cua tu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((lai ky) OR (sai ky)) sang ma hoi. hieu van cam duc ((hoa doanh) or (va danh)) dan cua tu*".
