• Performing a fuzzy search may retrieve terms with similar spellings: toc sach thue nang xa hoi. hieu ve ((cac xuc) or (chat xuc)) van hanh ((lai cua) OR (lai chau)) cu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach thue nang xa hoi. hieu ve ((cac xuc) OR (chat xuc)) van hanh ((lai cua) OR (lai chau)) cu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach thue nang xa hoi. hieu ve ((cac xuc) or (chat xuc)) van hanh ((lai cua) OR (lai chau)) cu*".
