You can now filter [AutoRAG](/autorag) search results by `folder` and `timestamp` using [metadata filtering](/autorag/configuration/metadata-filtering/) to narrow down the scope of your query.

This makes it easy to build [multitenant experiences](/autorag/how-to/multitenancy/) where each user can only access their own data. By organizing your content into per-tenant folders and applying a `folder` filter at query time, you ensure that each tenant retrieves only their own documents.

## Metadata attributes

You can currently filter by the `folder` and `modified_date` of an R2 object. Currently, custom metadata attributes are not supported.
You can currently filter by the `folder` and `timestamp` of an R2 object. Currently, custom metadata attributes are not supported.

### `folder`

The directory to the object. For example, the `folder` of the object at `llama/logistics/llama-logistics.mdx` is `llama/logistics/`. Note that the `folder` does not include a leading `/`.

Note that `folder` filter only includes files exactly in that folder, so files in subdirectories are not included. For example, specifying `folder: "llama/"` will match files in `llama/` but does not match files in `llama/logistics`.

### `modified_date`
### `timestamp`

The timestamp indicating when the object was last modified. Comparisons are supported using a 13-digit Unix timestamp (milliseconds), but values will be rounded to 10 digits (seconds). For example, `1735689600999` or `2025-01-01 00:00:00.999 UTC` will be rounded down to `1735689600000`, corresponding to `2025-01-01 00:00:00 UTC`.
