sourceBuilder = new SearchSourceBuilder(); // 设置查询条件 sourceBuilder.query(QueryBuilders.regexpQuery("message","xu[0-9]")); searchRequest.source(sourceBuilder); System.out.println("正则查询的DSL语句:"+sourceBuilder.toString()); // 同步查询 SearchResponse searchResponse = client.search(searchRequest, RequestOptions.DEFAULT); // 结果 searchResponse.getHits().forEach(hit -> { Map<String, Object> map = hit.getSourceAsMap(); String string = hit.getSourceAsString(); System.out.println("正则查询的Map结果:" + map); System.out.println("正则查询的String结果:" + string); }); System.out.println("\n=================\n"); }

查询测试结果

所有查询总数:6
普通查询的DSL语句:{"from":0,"size":5,"timeout":"60s","query":{"term":{"uid":{"value":"1234","boost":1.0}}}}

=================

或查询语句:{"query":{"bool":{"must":[{"bool":{"should":[{"term":{"uid":{"value":1234,"boost":1.0}}},{"term":{"uid":{"value":12345,"boost":1.0}}}],"adjust_pure_negative":true,"boost":1.0}},{"term":{"phone":{"value":"12345678909","boost":1.0}}}],"adjust_pure_negative":true,"boost":1.0}}}
或查询结果:{msgcode=1, uid=12345, phone=12345678909, message=qq, sendtime=2019-03-14 01:57:04}

=================

模糊查询语句:{"query":{"bool":{"must":[{"wildcard":{"message":{"wildcard":"xu","boost":1.0}}}],"adjust_pure_negative":true,"boost":1.0}}}
模糊查询结果:{msgcode=2, uid=12345, phone=123456789019, sendtime=2019-03-14 01:57:04, message=xuwujing study Elasticsearch}
模糊查询结果:{uid=123456, phone=12345678909, message=xu1, sendtime=2019-03-14 01:57:04}

=================

存在查询的DSL语句:{"query":{"exists":{"field":"msgcode","boost":1.0}}}
存在查询的Map结果:{msgcode=2, uid=12345, phone=123456789019, sendtime=2019-03-14 01:57:04, message=xuwujing study Elasticsearch}
存在查询的String结果:{"uid":12345,"phone":123456789019,"msgcode":2,"sendtime":"2019-03-14 01:57:04","message":"xuwujing study Elasticsearch"}
存在查询的Map结果:{msgcode=1, uid=12345, phone=12345678909, message=qq, sendtime=2019-03-14 01:57:04}
存在查询的String结果:{"uid":"12345","phone":"12345678909","message":"qq","msgcode":"1","sendtime":"2019-03-14 01:57:04"}

=================

范围查询的DSL语句:{"query":{"range":{"sendtime":{"from":"2019-01-01 00:00:00","to":"2019-12-31 23:59:59","include_lower":true,"include_upper":true,"boost":1.0}}}}
范围查询的String结果:{"uid":12345,"phone":123456789019,"msgcode"
