• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky ((dang xa) OR (dang ha)) hoi. hieu van cam tuc va van vat ((cuu tre) or (cau tren))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky ((dang xa) OR (dang ha)) hoi. hieu van cam tuc va van vat ((cuu tre) OR (cau tren)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky ((dang xa) OR (dang ha)) hoi. hieu van cam tuc va van vat ((cuu tre) or (cau tren))".
