• Performing a fuzzy search may retrieve terms with similar spellings: thuat ((anh ky) OR (anh y)) nang ma hoa. ((hieu van) or (thien van)) dao duc van anh ban cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat ((anh ky) OR (anh y)) nang ma hoa. ((hieu van) OR (thien van)) dao duc van anh ban cua tre.
