# Faceting

> Learn how to aggregate and count values in your search results

## Overview

Faceting gives you total counts for any field in your results. It helps you build filters and understand how your data is grouped. You can:

* Count transactions per currency
* See how many transactions are in each status
* Group balances by ledger or identity
* Break transactions into date or amount ranges

***

## Quick start

Here's a basic faceting request that shows the total counts for the `status` and `currency` fields:

<CodeGroup>
  ```bash cURL theme={"system"}
  curl -X POST "http://YOUR_BLNK_INSTANCE_URL/search/transactions" \
    -H "X-Blnk-Key: YOUR_API_KEY" \
    -H "Content-Type: application/json" \
    -d '{
      "q": "*",
      "facet_by": "status,currency"
    }'
  ```

  ```json Response theme={"system"}
  {
    "facet_counts": [
      {
        "counts": [
          {
            "count": 1000,
            "highlighted": "APPLIED",
            "value": "APPLIED"
          },
          {
            "count": 1500,
            "highlighted": "INFLIGHT",
            "value": "INFLIGHT"
          }
          {
            "count": 500,
            "highlighted": "REJECTED",
            "value": "REJECTED"
          }
        ],
        "field_name": "status",
        "stats": {
          "total_values": 1
        }
      },
      {
        "counts": [
          {
            "count": 876,
            "highlighted": "GBP",
            "value": "GBP"
          },
          {
            "count": 821,
            "highlighted": "EUR",
            "value": "EUR"
          },
          {
            "count": 803,
            "highlighted": "USD",
            "value": "USD"
          }
        ],
        "field_name": "currency",
        "stats": {
          "total_values": 3
        }
      }
    ]
  ```
</CodeGroup>

| **Field**      | **Description**                              |
| :------------- | :------------------------------------------- |
| `field_name`   | The field being faceted.                     |
| `value`        | A unique value found in that field.          |
| `count`        | Number of documents that have this value.    |
| `counts`       | The full list of values and their counts.    |
| `total_values` | How many unique values exist for this field. |

## Combining faceting with filters

Faceting becomes more powerful when combined with filters. You can facet on one field while filtering on others to analyze specific subsets of your data.

<CodeGroup>
  ```bash USD transactions by status theme={"system"}
  curl -X POST "http://YOUR_BLNK_INSTANCE_URL/search/transactions" \
    -H "X-Blnk-Key: YOUR_API_KEY" \
    -H "Content-Type: application/json" \
    -d '{
      "q": "*",
      "filter_by": "currency:=USD",
      "facet_by": "status"
    }'
  ```

  ```bash Customer balances by currency theme={"system"}
  curl -X POST "http://YOUR_BLNK_INSTANCE_URL/search/balances" \
    -H "X-Blnk-Key: YOUR_API_KEY" \
    -H "Content-Type: application/json" \
    -d '{
      "q": "*",
      "filter_by": "identity_id:=idt_28f25ef6-2e0d-4fa6-891c-37fc409d654e",
      "facet_by": "currency"
    }'
  ```
</CodeGroup>

The example above allows you to answer questions like:

* "Of all my USD transactions, how many are in each status?"
* "For this specific customer, how many balances do they have in each currency?""

***

## Faceting on metadata fields

You can also facet on metadata objects.

```bash Facet on metadata fields theme={"system"}
curl -X POST "http://YOUR_BLNK_INSTANCE_URL/search/transactions" \
  -H "X-Blnk-Key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "q": "*",
    "facet_by": "meta_data.transaction_type,meta_data.payment_method"
  }'
```

<Tip>
  Always use dot notation to access nested metadata fields: `meta_data.field_name`
