• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ((y nang) or (ly nang)) x hoi. hieu van lam tuc gia thanh vinh ((cuu tre) OR (cau treo))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((y nang) OR (ly nang)) x hoi. hieu van lam tuc gia thanh vinh ((cuu tre) OR (cau treo))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((y nang) or (ly nang)) x hoi. hieu van lam tuc gia thanh vinh ((cuu tre) OR (cau treo))*".
