Hi, Lucene never appends to files, so this is not something that is not used anywhere. Whenever Lucene updates something in the index, it creates a new file. In earlier Lucene version there was seeking supported, but this is removed since Lucene 4.7 (I think). This was just a hack around some problems (requirement to modify header after writing file), but this is now solved, so seek() was removed completely. And it won't come back.
