• Performing a fuzzy search may retrieve terms with similar spellings: so ((sach ty) OR (sach y)) nang x hoi. lieu va dau truc ban thanh do ((cuu tre) or (cua tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so ((sach ty) OR (sach y)) nang x hoi. lieu va dau truc ban thanh do ((cuu tre) OR (cua tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so ((sach ty) OR (sach y)) nang x hoi. lieu va dau truc ban thanh do ((cuu tre) or (cua tre))*".
