By default, the Blossom spider looks for a sitemap.xml file in each folder it processes. (If desired, this behavior can be turned off from the Search Configuration page.) Recently we discovered that at least one sitemap generator creates a file header that caused our sitemap parser to fail. As a result, some sitemaps were not followed.
The latest spider update has fixed this problem, allowing more sitemaps to be read. Your indexes may now include files that previously were not found.
