• Performing a fuzzy search may retrieve terms with similar spellings: te ((sach ty) OR (sach tu)) nang ma hoi. hieu ve ((cam tuc) or (cam tu)) va hanh dai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ty) OR (sach tu)) nang ma hoi. hieu ve ((cam tuc) OR (cam tu)) va hanh dai cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ty) OR (sach tu)) nang ma hoi. hieu ve ((cam tuc) or (cam tu)) va hanh dai cuu tre".
