We are using EFK as log management for our application. I am playing with API of elastic search, while doing this I have few queries to get clarify.
**localhost:9200/\_cat/indices?bytes=b&s=store.size:desc&v**
getting output with index with storage values.
health status index uuid pri rep docs.count docs.deleted store.size pri.store.size

By default you will get only 10 documents
you can supply size parameter to retrieve more
**localhost:9200/logstash-2020.06.14/\_search?size=100**

@ylasri Thanks for your response.
Now understand to get this data, kindly share any links if you have any for more optimization with dates or size i can use it API and also for my research.
