Elasticsearch根据条件统计结果数量
post ip:port/index/type/_search{ “from”: 0, “size”: 0, “query”: { “bool”: { “must”: [{ “match_phrase”: { “name”: { “query”: “aaaa”, “slop”: 0, “boost”: 1 } } }, { “range”: { “startTime”: { “from”: 1661616000391, “to”: null, “include_lower”: true, “include_upper”: true, “boost”: 1 } } } ] } }, “_source”: { “includes”: [ “COUNT” ], “excludes”: [] }, “aggregations”: { “COUNT(*)”: { “value_count”: { “field”: “_index” } } }}
java代码:
SearchSourceBuilder sourceBuilder = new SearchSourceBuilder();AggregationBuilder sumAggregationBuilder = AggregationBuilders.count(“count”).field(“_index”);sourceBuilder.aggregation(sumAggregationBuilder);BoolQueryBuilder queryBuilder = QueryBuilders.boolQuery();//查询条件queryBuilder.must(QueryBuilders.matchPhraseQuery(“name.keyword”,name));queryBuilder.must(QueryBuilders.rangeQuery(“startTime”).gte(startTime));//设置条件和结果数量sourceBuilder.query(queryBuilder).from(0).size(0);//查询索引对象SearchRequest searchRequest = new SearchRequest(index).types(type).source(sourceBuilder);//不同版本请求ES的方式不一样SearchResponse response = client.search(searchRequest).actionGet();SearchResponse response = client.getClient().search(rq,RequestOptions.DEFAULT);//返回结果long total = response.getHits().getTotalHits(); 而不去欣赏今天就开在我们窗口的玫瑰。
