2、Histogram Aggregation:根据数值阶梯分组,与日期类似 3、Terms Aggregation:根据词条内容分组,词条内容完全匹配的为一组 4、Range Aggregation:数值和日期的范围分组,指定开始和结束,然后按段分组 综上所述,我们发现bucket aggregations 只负责对数据进行分组,并不进行计算,因此往往bucket中往往会嵌套另一种聚合:metrics...
"filter": { "term": { "type": "t-shirt" } }, "aggs": { "avg_price": { "avg": { "field": "price" } } } } } } 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 8、稀有值查询 Rare terms 示例:查询桶中最多包含2条记录的类型genre。 GET /_search { "aggs": { "gen...
除了使用nested进行普通查询外,nested也支持聚合查询,同样是上面的例子,现在做一个对年龄聚合的操作: GET my_index/_search { "aggs": { "nestedAgg": { "nested": { "path": "user" }, "aggs": { "ageAgg": { "terms": { "field": "user.age.keyword", "size": 10 } } } } } } (五)...

ElasticSearch - 嵌套对象 nested ElasticSearch 桶内排序 bucket_sortbucket_sort 类似于aggs的一个聚合函数 实际操作json构建 {"query":{"range":{"pay_time":{"gte":"2020-11-01","lt":"2020-11-12","format":"yyyy-MM-dd"}}},"aggs":{"temr_cityCode":{"terms":{"field":"city_code"},"ag...
"terms": { "field":"tags","size":3}, "aggs": { "top_tag_hits": { "top_hits": {//用 tags 字段分组,每个 tag(即一个分组)只显示最后一个问题,并且只在 _source 中保留 title 字段"sort": [ { "last_activity_date": { "order":"desc"} ...
使用nested结构非常简单,指定字段的type为nested即可。下面的例子中定义了一个名为labels的nested结构,其中包含两个字段,分别是key和value。 "mappings": {"demoType": {"labels": {// 字段类型设置为nested"type":"nested","properties": {"key": {"type":"keyword"},"value": {"type":"keyw...
POST /product/_search { "size": 0, "aggs": { "theme": { "nested": { "path": "themes"//嵌套对象 }, "aggs": { "agg_category": { "terms": { "field": "themes.category"//聚合对象 }, "aggs": { "agg_name": { "nested": { "path": "themes.items"//嵌套对象的嵌套对象 }...
"aggs": { "labels_nested": { "nested": { "path": "labels" }, "aggs": { "nested_value": { "terms": { "field": "labels.value" } } } } } } 这个查询将会得到下面类似的结果: { "aggregations": { "labels_nested": {
{"agg_name1":{"terms":{"field":"ownerId","size":3},"aggs":{"aggs_nested_name1":{"nested":{"path":"callStatInfo"},"aggs":{"aggs_sub_name1":{"stats":{"field":"callStatInfo.totalCallOutDuration"}},"aggs_sub_name2":{"avg":{"field":"callStatInfo.totalCallOutNum"}}} 说...
