ElasticSearch更新Api不会增加docs.deleted计数

Question

我创建了一个名为＆＃34; second＆＃34; ，

health status index  pri rep docs.count docs.deleted store.size pri.store.size 
yellow open   second   5   1          2            0      5.5kb          5.5kb 
yellow open   first    5   1          2            0      5.3kb          5.3kb 

我有两个文件，我创建了一个这样的新文档。

curl -X PUT  http://localhost:9200/second/obj/3 -d '{"name": "abc","age":"25"}'

我通过使用post方法调用相同的Api来更新文档

curl -X POST  http://localhost:9200/second/obj/3 -d '{"name": "xyz","age":"25"}'

它已成功更新

{"_index":"second","_type":"obj","_id":"3","_version":2,"created":false}

但现在我看到curl http://localhost:9200/_cat/indices?v

它给我输出

health status index  pri rep docs.count docs.deleted store.size pri.store.size 
yellow open   second   5   1          3            0     10.6kb         10.6kb 
yellow open   first    5   1          2            0      5.3kb          5.3kb

它应该增加＆＃34; docs.deleted＆＃34;算了，为什么它没有增加？

编辑：正如要求附加api调用的输出

我跑的时候

curl 'http://localhost:9200/second/_segments?pretty'
