It can be tricky.... eg if segments share doc stores, I think you can't always recover that.
But this index seems not to have separate doc stores (no *.cfx), so, I think in theory one could regenerate the segment metadata (SegmentInfo) from the index files, but I don't know that anyone has created this yet. Also, it could in general result in re-attaching segments that had been merged away (ie, causing duplicates in the index).
