Comment

Elasticsearch Java API has full-fledged implementation of Query DSL in a form of QueryBuilders and Query

Builder classes so writing (and maintaining) the complex queries is exceptionally easy

final SearchResponse response = client
.prepareSearch("catalog")
.setTypes("books")
.setSearchType(SearchType.DFS_QUERY_THEN_FETCH)
.setQuery(query)
.setFrom(0)
.setSize(10)
.setFetchSource(
new String[] { "title", "publisher" }, /* includes */
new String[0] /* excludes */
)
.setTimeout(TimeValue.timeValueMillis(100))
.get(TimeValue.timeValueMillis(200));
assertThat(response.getHits().hits())
.withFailMessage("Expecting at least one book to be returned")
.extracting("sourceAsString", String.class)
.hasOnlyOneElementSatisfying(source -> {
assertThat(source).contains("Elasticsearch: The Definitive Guide.");
});
