Not quite sure what you mean by "destroy". I can use a delete-by-query with *:* and mark all docs in my index deleted. Search results will return nothing but it's still a valid index, it just consists of all deleted docs. All the segments may be removed even in the absence of an optimize due to segment merging.
But it's still a perfectly valid index, it just has nothing in it. Are you seeing a real problem here or are you just wondering why all your segment files disappeared?
