• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky dang cau hoi. hieu ve ((cam tuc) or (nam thuc)) va thanh toan ((cuu tre) OR (cua tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky dang cau hoi. hieu ve ((cam tuc) OR (nam thuc)) va thanh toan ((cuu tre) OR (cua tre)).
