Hi @MNB_1101  
You can use the `size` parameter to return more terms, up to the [search.max\_buckets](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-settings.html#search-settings-max-buckets) limit.

If your data contains 100 or 1000 unique terms, you can increase the `size` of the `terms` aggregation to return them all. If you have more unique terms and you need them all, use the [composite aggregation](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-bucket-composite-aggregation.html) instead.

Larger values of `size` use more memory to compute and, push the whole aggregation close to the `max_buckets` limit. You’ll know you’ve gone too large if the request fails with a message about `max_buckets` .

For ex.

```nohighlight
{
  "aggs": {
    "products": {
      "terms": {
        "field": "product",
        "size": 100,
        "show_term_doc_count_error": true
      }
    }
  }
}

```

Thank you for your answer, but I can't change this value when I use create new rule in Kibana, when I define new rule that rule type "Threshold" is selected, by default size is 10:

```auto
{
"aggregations": {
"eventActionGroup": {
"terms": {
"order": {
"_count": "desc"
},
"size": 10,
....

```

Please don't create multiple topics on the same question - [How can I change the default size of the returned aggregations (10) in kibana “create new rule”? - #3 by MNB\_1101](https://discuss.elastic.co/t/how-can-i-change-the-default-size-of-the-returned-aggregations-10-in-kibana-create-new-rule/303860/3)
