• Performing a fuzzy search may retrieve terms with similar spellings: nuoc sach y ((nang xa) OR (lang xa)) hoi. hieu ke cau phuc van thang di ((cua tre) or (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: nuoc sach y ((nang xa) OR (lang xa)) hoi. hieu ke cau phuc van thang di ((cua tre) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "nuoc sach y ((nang xa) OR (lang xa)) hoi. hieu ke cau phuc van thang di ((cua tre) or (cua te))".
