# Azure AI Search

Batch process all your records to store structured outputs in an Azure AI Search account.

The requirements are as follows.

The following video shows how to fulfill the minimum set of Azure AI Search requirements:

Here are some more details about these requirements:

* The endpoint and API key for Azure AI Search. [Create an endpoint and API key](https://learn.microsoft.com/azure/search/search-create-service-portal).
* The name of the index in Azure AI Search. [Create an index](https://learn.microsoft.com/rest/api/searchservice/create-index).

  The Azure AI Search index that you use must have an index schema that is compatible with the schema of the documents
  that Unstructured produces for you. Unstructured cannot provide a schema that is guaranteed to work in all
  circumstances. This is because these schemas will vary based on your source files' types; how you
  want Unstructured to partition, chunk, and generate embeddings; any custom post-processing code that you run; and other factors.

  You can adapt the following index schema example for your own needs. Be sure to replace `<number-of-dimensions>`
  (in three locations in the following example) with the number of dimensions of the embedding model you are using:

The Azure AI Search connector dependencies:

```bash CLI, Python theme={null}
pip install "unstructured-ingest[azure-ai-search]"
```

You might also need to install additional dependencies, depending on your needs. [Learn more](/open-source/ingestion/ingest-dependencies).

These environment variables:

* `AZURE_SEARCH_ENDPOINT` - The endpoint URL for Azure AI Search, represented by `--endpoint` (CLI) or `endpoint` (Python).
* `AZURE_SEARCH_API_KEY` - The API key for Azure AI Search, represented by `--key` (CLI) or `key` (Python).
* `AZURE_SEARCH_INDEX` - The name of the index for Azure AI Search, represented by `--index` (CLI) or `index` (Python).

Now call the Unstructured CLI or Python. The source connector can be any of the ones supported. This example uses the local source connector.

This example sends files to Unstructured for processing by default. To process files locally instead, see the instructions at the end of this page.

For the Unstructured Ingest CLI and the Unstructured Ingest Python library, you can use the `--partition-by-api` option (CLI) or `partition_by_api` (Python) parameter to specify where files are processed:

* To do local file processing, omit `--partition-by-api` (CLI) or `partition_by_api` (Python), or explicitly specify `partition_by_api=False` (Python).

  Local file processing does not use an Unstructured API key or API URL, so you can also omit the following, if they appear:

  * `--api-key $UNSTRUCTURED_API_KEY` (CLI) or `api_key=os.getenv("UNSTRUCTURED_API_KEY")` (Python)
  * `--partition-endpoint $UNSTRUCTURED_API_URL` (CLI) or `partition_endpoint=os.getenv("UNSTRUCTURED_API_URL")` (Python)
  * The environment variables `UNSTRUCTURED_API_KEY` and `UNSTRUCTURED_API_URL`

* To send files to the legacy [Unstructured Partition Endpoint](/api-reference/legacy-api/partition/overview) for processing, specify `--partition-by-api` (CLI) or `partition_by_api=True` (Python).

  Unstructured also requires an Unstructured API key and API URL, by adding the following:

  * `--api-key $UNSTRUCTURED_API_KEY` (CLI) or `api_key=os.getenv("UNSTRUCTURED_API_KEY")` (Python)
  * `--partition-endpoint $UNSTRUCTURED_API_URL` (CLI) or `partition_endpoint=os.getenv("UNSTRUCTURED_API_URL")` (Python)
  * The environment variables `UNSTRUCTURED_API_KEY` and `UNSTRUCTURED_API_URL`, representing your API key and API URL, respectively.

  <Note>
    You must specify the API URL only if you are not using the default API URL for Unstructured Ingest, which applies to **Let's Go**, **Pay-As-You-Go**, and **Business SaaS** accounts.

    The default API URL for Unstructured Ingest is `https://api.unstructuredapp.io/general/v0/general`, which is the API URL for the legacy[Unstructured Partition Endpoint](/api-reference/legacy-api/partition/overview). However, you should always use the URL that was provided to you when your Unstructured account was created. If you do not have this URL, email Unstructured Support at [support@unstructured.io](mailto:support@unstructured.io).

    If you do not have an API key, [get one now](/api-reference/legacy-api/partition/overview).

    If you are using a **Business** account, the process
    for generating Unstructured API keys, and the Unstructured API URL that you use, are different.
    For instructions, see your Unstructured account administrator, or email Unstructured Support at [support@unstructured.io](mailto:support@unstructured.io).
