We rebuild the search index every fifteen minutes, so if you add new files or import files they may not show up in file search results straight away. We do this in order to provide the fastest possible search experience which we can only do by caching the search index. Providing real time search could overwhelm our database due to the large number of new files added constantly.
However you can see a list of most recently added files by using the "Newest Files" smart list from the "Filter by" dropdown in the file manager.
