I *think* I saw that random uuid-style strings of alphanumerics and underscores or dashes also sorted differently. I
didn'tstop to take time to definitively verify that, but just kept on with re-indexing as quickly as possible. But I
definitelysaw symptoms of corrupted indexes until the reindex completed, and they appeared with the OS upgrade, not
before,*as far as I know*
