lucene will never modify old segment files, it just flushes into a new segment or merges old segments into new one. after merging, old segments will be deleted. once a file(such as fdt and fdx) is generated. it will never be re-generated. the only possible is that in the generating stage, there is something wrong. or it's deleted by other programs such as wrongly deleted by human.
