94.7. 搜索示例

根据特定字段和值搜索，使用 Operation 'Search'。传递查询 JSON String 或 Map

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);

使用 Map 搜索特定字段。

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);
