For what you know, is this behaviour which you defined "typical" described deeply somewhere?
It is foundamental for me to better understand it even to know how big an index can grow, in a way that I can allocate the right disk space.

Anyway here it is the size of each sub-directory in my index, please note the bigger one, 25G, is it normal? ...repository/workspaces/default/index$ du -h . 2.5G ./_12ey1 14M ./_1dr9s 20M ./_1dr8d 2.8G ./_1b9pj 5.8M ./_1drqc 19M ./_1dr4q 2.5G ./_17lmu 4.0M ./_1drmx 11M ./_1drbf 4.3M ./_1drok 13M ./_1drq1 40K ./_1drqe 11M ./_1drhc 260M ./_1dr3g 664M ./_1by44 2.5G ./_14tet 281M ./_1c4wj 25G ./_zzgq 274M ./_1d2nc 638M ./_1ctf0 580K ./_1drqf 304K ./_1drqd 6.5M ./_1dr6m 325M ./_1djfp 37G I tried also to download index directory to my local machine, to inspect them with Luke which I know a bit, but for network problem the download always interrupts. > What is your segment size limit?

If yes I'm using the default that is 10, read here https://jackrabbit.apache.org/archive/wiki/JCR/Search_115513504.html Max segment I don't know, where could I see it?

However, it is hard to predict more without knowing more data. What is your segment size limit? Have you changed the default merge frequency or max segments configuration? Would you have an estimate of ratio of number of segments reaching max limit / total segments?
