Well, if nothing is going on at all, it's hard to see why the index would increase. So I suspect _something_ is going on. Possibilities:
1> you have indexing activity going on. Even if it's just replacing docs that already exist, which is actually an add and a delete the index will grow for a while; the deleted info isn't removed from the index until the segment is merged, which happens unpredictably (well, actually predictably but not on a schedule you enforce). So the index would grow/shrink/grow/shrink. Do you have automatic process in the background that push docs to the index? 2> You forceMerge (optimize), in which case the index will at least double in size temporarily. 3> You are replicating. While the replication goes on, especially if your index has changed greatly, then your index could double. None of these fit the symptoms you describe very well mind you. It's suspicious that these increases last long enough for you to see them predictably in the morning, unless, say, a background process indexes things regularly and you always look at the same time... unlikely at best. But the fact that your index goes from 18G to 8G strongly suggests that you're doing a forceMerge/optimize when you see it bump up to 18G.
