OpenDistro Alert Error- 1.7.0 - field expansion matches too many fields

Hi Team,

I am trying to use Open Distro’s alerting and getting the following error:

“caused_by”: {
“reason”: “field expansion matches too many fields, limit: 1024, got: 1220”,
“type”: “illegal_argument_exception”

after doing some researching ( ref - Elasticsearch - set max_clause_count - Stack Overflow) added the search settings indices.query.bool.max_clause_count to the elasticsearch.yml config. This caused the elasticsearch.service to not start and timeout.

I am looking to get a solution that will allow me to create Alerts with out getting the above mentioned error from Open Distro.
