• Performing a fuzzy search may retrieve terms with similar spellings: toc sach ky danh xa hoi. hieu va ((cam duc) or (pham duc)) ((ban danh) OR (ban dan)) hai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach ky danh xa hoi. hieu va ((cam duc) OR (pham duc)) ((ban danh) OR (ban dan)) hai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach ky danh xa hoi. hieu va ((cam duc) or (pham duc)) ((ban danh) OR (ban dan)) hai cua tre*".
