from("direct:search")
  .to("elasticsearch-rest://elasticsearch?operation=Search&indexName=twitter&indexType=tweet");

<route>
    <from uri="direct:search" />
    <to uri="elasticsearch-rest://elasticsearch?operation=Search&indexName=twitter&indexType=tweet"/>
</route>

String query = "{\"query\":{\"match\":{\"content\":\"new release of ApacheCamel\"}}}";
SearchHits response = template.requestBody("direct:search", query, SearchHits.class);

Map을 사용하여 특정 필드에서 검색합니다.

Map<String, Object> actualQuery = new HashMap<>();
actualQuery.put("content", "new release of ApacheCamel");

Map<String, Object> match = new HashMap<>();
match.put("match", actualQuery);

Map<String, Object> query = new HashMap<>();
query.put("query", match);
SearchHits response = template.requestBody("direct:search", query, SearchHits.class);
