elasticsearch - 如何使用Elasticsearch Java RestHighLevelClient API创建 bool 查询

如何在下面使用bool创建RestHighLevelClient查询？

我的尝试未返回任何内容:

BoolQueryBuilder query = boolQuery()
                .must(queryStringQuery(queryString).analyzeWildcard(true).defaultField("*"))
                .must(rangeQuery("timestamp").gte(fromTs).lte(toTs).format("epoch_millis")
                );

我想要

"query":{
      "bool":{
         "must":[
            {
               "query_string":{
                  "query":"foo:evlis AND bar:beatles",
                  "analyze_wildcard":true,
                  "default_field":"*"
               }
            },
            {
               "range":{
                  "timestamp":{
                     "gte":1549360021398,
                     "lte":1549446421398,
                     "format":"epoch_millis"
                  }
               }
            }
         ],
         "filter":[

         ],
         "should":[

         ],
         "must_not":[

         ]
      }
   }

更新
我已启用org.elasticsearch.client上的调试日志记录，并可以看到此调试输出。 当我单击调试日志中的链接时，可以看到结果。

2019-02-07 19:20:11.351 DEBUG 17524 --- [/O dispatcher 1] org.elasticsearch.client.RestClient      : request

returned [HTTP/1.1 200 OK]

但是 searchResponse.getHits()为空，找到0次？？？

    private void printResult(SearchResponse response) {
        System.out.println("=== HTTP Request ===");
        System.out.println("status: " + response.status());
        System.out.println("took: " + response.getTook());
        System.out.println("timed_out: " + response.isTimedOut());

        System.out.println("\n=== Hits ===");
        final SearchHits hits = response.getHits();
        System.out.println("total_hits: " + hits.getHits().length);

        List<Journey> journeys = new ArrayList<>();
        for (SearchHit hit : hits.getHits()) {
            System.out.println("\n=== Documents ===");
            System.out.println("index: " + hit.getIndex());
            System.out.println("type: " + hit.getType());
            System.out.println("id: " + hit.getId());
            System.out.println("source: " + hit.getSourceAsString());
        }
    }

输出量

=== HTTP Request ===
status: OK
took: 19ms
timed_out: false

=== Hits ===
total_hits: 0

最佳答案

脚步:

创建一个新对象SearchSourceBuilder sourceBuilder。

创建BoolQueryBuilder的新对象boolQueryBuilder。

使用QueryBuilders将boolQueryBuilder添加到queryStringQuery中。

使用QueryBuilders将boolQueryBuilder添加到rangeQuery中。

将boolQueryBuilder添加为sourceBuilder的查询。

因此，您的查询翻译为:

SearchSourceBuilder sourceBuilder = new SearchSourceBuilder();
BoolQueryBuilder boolQueryBuilder = new BoolQueryBuilder();
boolQueryBuilder.must(
    QueryBuilders.queryStringQuery("foo:evlis AND bar:beatles").defaultField("*")
        .analyzeWildcard(true));
boolQueryBuilder.must(
    QueryBuilders.rangeQuery("timestamp").gte(1549360021398l).lte(1549446421398l)
        .format("epoch_millis"));
sourceBuilder.query(boolQueryBuilder);
