This probably answers your question: > ---

@magnusbaeck Well i create a aggs "size": 0, "aggs" : { "user-ids" : { "terms" : { "field" : "user-id" } } } But it returns me only 12 id's. How can i increase numbers of id's in my response? (i have it apx. 7000) And i want to see all of them. The respond looks like this: "aggregations": { "user-ids": { "doc\_count\_error\_upper\_bound": 137, "sum\_other\_doc\_count": 97335, "buckets": [ { "key": 572773, "doc\_count": 646 }, { "key": 665035, "doc\_count": 533 }, { "key": 672046, "doc\_count": 425 }, { "key": 672870, "doc\_count": 403 }, { "key": 192596, "doc\_count": 364 }, { "key": 588616, "doc\_count": 361 }, { "key": 401020, "doc\_count": 348 }, { "key": 664634, "doc\_count": 347 }, { "key": 673037, "doc\_count": 340 }, { "key": 669806, "doc\_count": 334 } ] } } ---

I mean I want to see all buckets not only 10. ---

this should help you: [https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-bucket-terms-aggregation.html#\_size](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-bucket-terms-aggregation.html#_size) Note that it is not a good idea to set `size` to `0` as this can lead to memory issues. If you are expecting approx 7000 values I would set `size` to `10000`. Note that this `size` parameter is inside the `terms` aggregation and is not the same as the `size` parameter you already have in your request. ---

@colings86 Well, there is no any solution like \_all in size? ---

If you want the `user-name` field of _all_ documents (i.e. no aggregation at all) try this: ``` POST /name-of-your-index/_search { "query": { "constant_score": { "filter": { "exists": { "field": "user-name" } } } }, "fields": ["user-name"], "size": 10000 } ``` (If you don't have an reasonable accurate upper bound on the number of documents to return, have a look at the [scan and scroll API](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-request-scroll.html). ---

@magnusbaeck Sorry I can't find answer. I have request POST /name-index/\_search { "filter": { "term": { "event\_type": "03\_finish\_tutorial\_battle1" } } } and i want to see all my 1235 document in response (something like "size": "\_all"). Is it possible? ---

To get _all_ documents, set `size` to zero. Or what's the problem? ---
