## Search a knowledge store by item collection

When you search a knowledge store, you can now limit the search to the items in specific item collections.

If a search matches more than 10,000 items, the platform returns a `422` error with the `metadata_filter_too_broad` code.

To use this feature, upgrade to the latest version of the Python or Node.js SDK:

**`Python SDK`**

```sh Python SDK
pip install --upgrade twelvelabs
```

**`Node.js SDK`**

```sh Node.js SDK
npm install twelvelabs-js@latest
```

For details, see the [Search a knowledge store](/v1.3/api-reference/knowledge-store-search/search) page in the API Reference section, or the SDK reference for [Python](/v1.3/sdk-reference/python/search-knowledge-store) and [Node.js](/v1.3/sdk-reference/node-js/search-knowledge-store).

## Introducing metadata, enrichment, and creation time filters for listing knowledge store items

You can now filter the items in a knowledge store when you list them. Use the `metadata`, `enrichment`, `created_at_gte`, and `created_at_lte` parameters to filter by custom metadata, enrichment values, and creation time.

To use this feature, upgrade to the latest version of the Python or Node.js SDK:

**`Python SDK`**

```sh Python SDK
pip install --upgrade twelvelabs

**`Node.js SDK`**

```sh Node.js SDK
npm install twelvelabs-js@latest
```

For details, see the [List knowledge store items](/v1.3/api-reference/knowledge-store-items/list) page in the API Reference section, or the SDK reference for [Python](/v1.3/sdk-reference/python/knowledge-store-items#list-knowledge-store-items) and [Node.js](/v1.3/sdk-reference/node-js/knowledge-store-items#list-knowledge-store-items).
