Limit the number of results returned by Elastic Search

How about using From/Size in order to return the requirement number of results:

GET /_search{    "from" : 0, "size" : 1000,    "query" : {        //your query    }}

You can just specify the size as an parameter.

GET /_search?size=1000{    "query" : {        //your query    }}

I know this question aged a little since it was asked, but i stumbled over this and i am surprised no one could give the correct answer.

Elasticsearch indices have an index module called max_result_window. You can find it in the documentation under dynamic index settings.

index.max_result_window
The maximum value of from + size for searches to this index. Defaults to 10000. Search requests take heap memory and time proportional to from + size and this limits that memory. See Scroll or Search After for a more efficient alternative to raising this.

So basically instead of limiting from or size (or a combination of those), you set max_result_window to 1000 and ES will only return a maximum of 1000 hits per request.

If you are using an index definition in a separate JSON file to create your index, you can set this value there under yourindexname.settings.index.max_result_window.

I hope this helps the folks still looking for a solution to this problem!
