Elastic Stack Elasticsearch
1

Here one client method creating problem for me. I went through java api of elastic search but still not getting that client() usage and node usage.
Please help me out.

Here is the syntax.
SearchResponse sr = node.client().prepareSearch()
.addAggregation(
AggregationBuilders.terms("by_country").field("country")
.subAggregation(AggregationBuilders.dateHistogram("by_year")
.field("dateOfBirth")
.dateHistogramInterval(DateHistogramInterval.YEAR)
.subAggregation(AggregationBuilders.avg("avg_children").field("children"))
)
)
.execute().actionGet();

I'd use the REST client: https://www.elastic.co/guide/en/elasticsearch/client/java-rest/current/index.html
