What is the use of esconfig.xml found in the vendormagentomodule-elasticsearchetc directory?

Does any one having any idea about esconfig.xml file exists in the vendormagentomodule-elasticsearchetc directory?

As per name suggests, it looks like it is related with words configuration with ElasticSearch but can we configure max_clause and mapping related configurations in that file.

< ?xml version="1.0" encoding="UTF-8" ?>
