SELECT FIELD1, field2, field3, field4 as average_dau, FIELD5 as mau, sum(field4)/ sum(FIELD5), sum (FIELD5)/ sum(FIELD4) FROM feed_searchc_mau WHERE ctime = { $ datatime }

这是一个 SQL 查询语句，它的目的是从名为 feed_searchc_mau 的数据表中选取特定日期（$datatime）的数据，并计算平均每日活跃用户数、月活跃用户数以及日均活跃用户数和日均用户数的比例。具体来说，该查询语句选取了 FIELD1、field2、field3、以及将 field4 重命名为 average_dau 和将 FIELD5 重命名为 mau 这五个字段，并对这些字段进行了计算和聚合操作。其中，sum(field4)/sum(FIELD5) 计算的是日均活跃用户数，而 sum(FIELD5)/sum(FIELD4) 则计算的是日均用户数。

将这个Elasticsearch查询写成JAVA中调用Elasticsearch的查询代码：GET tmall_dau_info_2023-03-03/_search { "aggs": { "groupbyisnew": { "terms": { "field": "is_new", "size": 2 } } }, "size": 0 }

以下是Java中调用Elasticsearch的查询代码：

SearchRequest searchRequest = new SearchRequest("tmall_dau_info_2023-03-03");
SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
TermsAggregationBuilder aggregationBuilder = AggregationBuilders.terms("groupbyisnew").field("is_new").size(2);
searchSourceBuilder.aggregation(aggregationBuilder);
searchSourceBuilder.size(0);
searchRequest.source(searchSourceBuilder);
SearchResponse searchResponse = client.search(searchRequest, RequestOptions.DEFAULT);

其中，client是Elasticsearch的Java客户端。
