query,根据查询条件,去计算文档的匹配度得到一个分数,并且根据分数进行排序,不会做缓存。【精准匹配度高】
filter,根据查询条件去查询文档,不去计算分数,而且filter会对经常被过滤的数据进行缓存。【查询效率会高】

# filter 查询
POST /sms-logs-index/_search
{
  "query": {
    "bool": {
      "filter": [
        {
          "term": {
            "corpName": "阿里3"
          }
        },
        {
          "range": {
            "fee": {
              "gte": 20
            }
          }
        }
      ]
    }
  }
}

Java


@Test
void filterQuery() throws Exception {
    String indexName = "sms-logs-index";
    RestHighLevelClient client = ESClient.getClient();

    //1. 创建SearchRequest对象
    SearchRequest request = new SearchRequest(indexName);

    //2. 指定查询条件
    SearchSourceBuilder builder = new SearchSourceBuilder();
    BoolQueryBuilder boolQuery = QueryBuilders.boolQuery();
    boolQuery.filter(QueryBuilders.termQuery("corpName","阿里3"));
    boolQuery.filter(QueryBuilders.rangeQuery("fee").gte(20));

    builder.query(boolQuery);
    request.source(builder);

    //3. 执行查询
    SearchResponse resp = client.search(request, RequestOptions.DEFAULT);

    //4. 输出返回值
    for (SearchHit hit : resp.getHits().getHits()) {
        System.out.println(hit.getSourceAsMap());
    }
}
