• Performing a fuzzy search may retrieve terms with similar spellings: te ((sach ky) or (sac ky)) ((sang xa) OR (lang xa)) hoi. hieu va cau trung va danh lai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ky) OR (sac ky)) ((sang xa) OR (lang xa)) hoi. hieu va cau trung va danh lai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ky) or (sac ky)) ((sang xa) OR (lang xa)) hoi. hieu va cau trung va danh lai cua te".
