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();
