Magento 2 EE elastic search module not enabled

Question

I am running Magento 2.1.2 Enterprise Edition instance.

I have installed and enabled elastic search on the same. When I click on TEST CONNECTION button it says Successful! Test Again?

However the search suggestions does not display product names.

Do I need some additional settings or information to pass to elastic search?

Configuration for Elastic Search in Admin:

name    "My First Node"
cluster_name    "mycluster1"
version 
number  "2.3.1"
build_hash  "bd980929010aef404e7cb0843e61d0665269fc39"
build_timestamp "2016-04-04T12:25:05Z"
build_snapshot  false
lucene_version  "5.5.0"
tagline "You Know, for Search"

Answer 1

I think Magento 2.x only supports Elasticsearch 2.3

We support Elasticsearch versions 1.4, 1.7, and 2.4. The default version is 1.7.

Which is a disappointment, because AWS supports 2.4.
