Our cluster is configured as follows (This is a AWS managed Elasticservice)

1. 8 data nodes
2. 8 Shards
3. 1 Replica shard

Here is an example of index:

> green open service-logs-2017-12-10 ouyQ9Ew2SQQ 8 1 348663916 12687396 185.6gb 92.8gb

To optimize the search I wanted to merge the segments into one.

Here is the command I used to initiate force merge:

> curl -XPOST \<\>/service-logs-2017-12-10/\_forcemerge?max\_num\_segments=1

Now when I check the number of segments, I still see huge number of segments:

> curl \<\>/\_cat/segments | grep service-logs-2017-12-12 | wc -l  
> OUTPUT: 247

This includes primary and replica but this figure should be 2 after force merge.

Is there something I'm missing here?

Looks like there are some problem with AWS, new queries are working. Sorry for the post.
