Hi, I move to ES 5.4 from ES 1.7 recently and it seems to me that some configuration was changed. Like index.merge.policy.*
I used to set this in elasticsearch.yml but in 5.4 has been moved as index settings.
#1. Does this mean that I can set different merge policy params for the different index?
#2. What is the purpose to move these settings?
Thanks in advance.
