My index contains the "IP" field. While there are ~4000 records in my index, there are only ~10 unique IPs in it. I want an API call which will return the frequency of occurrence of each IP in the index.

I have developed a visualization for the same, but I need the API call too.

Also, is there a way to extract API calls used in the visualizations?

Here's a solution I've tried.

```
GET /trial23/_search
{
  "aggs": {
    "path_count": {
      "terms": {
        "field": "path.keyword",
        "size": 35
      }
    }
  },
  "size": 0
}

```

The output is like:

```
{
  "took": 247,
  "timed_out": false,
  "_shards": {
    "total": 5,
    "successful": 5,
    "skipped": 0,
    "failed": 0
  },
  "hits": {
    "total": 47673976,
    "max_score": 0,
    "hits": []
  },
  "aggregations": {
    "path_count": {
      "doc_count_error_upper_bound": 0,
      "sum_other_doc_count": 103,
      "buckets": [
        {
          "key": "/home/xyz/data/day=2018-09-20/hour=13/abc_000000_0.gz",
          "doc_count": 8166850
        },
        {
          "key": "/home/xyz/data/day=2018-09-20/hour=13/abc_6713_000002_0.gz",
          "doc_count": 8162160
        },
...

```

But I want to remove the initial fields like took, timed\_out etc., and only keep the buckets field.  
Any suggestions?
