"fuzzy" is a bit of an overstatement, all it does is match substrings with missing letters. If you type "orrange", it won't match. If you type "otange", it won't match. All it does is match the "oange" kind of typo (including "oe", which doesn't make any sense). This means that you'd get all kinds of weird suggestions that don't make sense as soon as your haystack has non-trivial size (like matching movie titles or artists), and might not find what you're looking for (no prioritization).
