set max\_merged\_segment to 5gb
set shard\_index\_buffer\_size to 5gb
set refresh to -1.
then most of the shard won't need to merge anymore.
and for sometime, manually refresh some shard. so the shard will be:
5gb, 5gb, 1mb, 5gb, 5gb, 2mb...
will these small segments got merged eventually?

`shard_index_buffer_size` applies to indexing, not merging.
`merged_segment` only applies to 1.X.
But as long as you aren't playing with merging settings, which you shouldn't need to do in 2.X, then yes, things will automatically merge.
