This is likely tricky to do correctly. E.g., MultiFieldQueryParser.getFieldQuery is invoked on whole chunks of text. If you search for:
apple orange I suspect it won't do what you want, since the whole string "apple orange" is passed to getFieldQuery. How do you want to handle e.g. a phrase query (user types "apple orange", with the double quotes)? Or a prefix query (app*)? Maybe you could instead override newTermQuery? In the example above it would be invoked twice, once for apple and once for orange. Finally, all this being said, making everything fuzzy is likely a big performance hit and often poor results (massive recall, poor precision) to the user!
