How to rewrite ElasticSearch DSL query with the Java API

Question

I have got a working query for ElasticSearch, but I have problems to execute the same query with the Java API of ElasticSearch.

How can I express the query below with the Java API of ElasticSearch?

---
size: 0

query:
  match_all: []

facets:
  age:
    statistical:
      field : timestamp

Can you post the exact problem that you are getting. Might be better if you post the Java API version of your attempted query. Here the documentation of Java API — aash

It should be something like:

client.prepareSearch("yourindex")
      .setTypes("yourtype")
      .setQuery(QueryBuilders.matchAllQuery())
      .addFacet(FacetBuilders.statisticalFacet("age").field("timestamp"))
      .setSize(0)
      .execute()
      .actionGet();

You can convert your query DSL to a JSON string, and then wrap it with QueryBuilders.wrapperQuery() or WrapperQueryBuilder(), finally do the query with Java API like this.

SearchResponse response = client.prepareSearch("yourIndex")
                                .setTypes("yourType")
                                .setQuery(dslQB)
                                .setFrom(currentItem)
                                .setSize(pageSize)
                                .execute()
                                .actionGet();
