[UPDATE: Users in comments and elsewhere are reporting similar issues with books and music, and Apple has now updated its status page.
Users are experiencing a problem with the App Store. We are investigating and will update the status as more information becomes available.]
[UPDATE 2: Apple says the issue is now resolved.]
A number of Reddit and Twitter users are reporting problems searching both iOS and Mac App Stores, with major iOS apps like Star Wars, Spotify and Google Apps failing to show up in search results – and even Apple’s own Xcode failing to show in searches of the Mac App Store. I’m seeing the same issues myself …
Others are reporting incorrect search results, such as iPhone apps being shown in iPad-only searches and vice-versa.
App Store searches are pretty broken at the best of times, but this does appear to be a specific glitch. At the time of writing, Apple’s status page is not yet showing the issue (update: it is now), but it’s typical for the page to be updated some time after users report problems. However, Apple Support has stated that it is aware of an ongoing issue with search and is working to resolve the problem. It has confirmed that no apps have been pulled from the store.
