I am trying to pull list of all doc\_ids in Elasticsearch index. the index contains 15 million docs, I am only interested in doc\_id. I have set search query in java by setting "size" parameter to 15 million, but i got exception the maximum size is "10000". any idea how i can achieve this task?

I am using simple httpPost request to submit the query as follows:

"stored\_fields": ["au.id","au.doc\_count"],  
"query": {  
"match\_all": {}  
}

Hi @telebh,

you should be able to pull out all the ids using a scroll search, see:
