• Performing a fuzzy search may retrieve terms with similar spellings: nuoc sac ky nang ma hoi. hieu ve ((canh chuc) OR (anh thuc)) van ((thang di) or (tang di)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: nuoc sac ky nang ma hoi. hieu ve ((canh chuc) OR (anh thuc)) van ((thang di) OR (tang di)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "nuoc sac ky nang ma hoi. hieu ve ((canh chuc) OR (anh thuc)) van ((thang di) or (tang di)) cua tre".
• Adding a wildcard symbol may retrieve word variants: nuoc sac ky nang ma hoi. hieu ve ((canh chuc) OR (anh thuc)) van ((thang di) or (tang di)) cua tre*.
