Fix also deals with spacing issues
Apple has made changes to the App Store search engine in recent weeks that have improved its ability to cope with typos, sources note. Typically this means that using one or two wrong letters will still turn up the proper app. The store is now also able to ignore spaces, for example successfully finding QuizUp if someone searches for "Quiz Up" instead.
While mostly a convenience for the public, the tweaks may be of major importance to developers, who depend on their apps being as easily discoverable as possible. Until this month, Google Play's automatic spellchecking offered a distinct advantage. iOS developers generally had to include misspellings in their keywords to catch typos.
