I have an index in my Elasticsearch version 6.4.2. I was able to view the index by calling http://:9200/logstash-2018.12.20.
I can see that this index has a mapping of "doc" entities.
"mappings": {
"doc": {.........
But when I try to search in this index using this end point GET http://:9200/logstash-2018.12.20/doc/_search, I just get an error "Could not get any response. There was an error connecting.."
Is there a setting I need to verify? What can i do to fix this? Thanks.
