We’re using the querystring query API, allowing filters by field like so: references.name:epub or like so last-seen:>now-1M.

An up-to-date list of available fields can be found in the index mapping definition for files and directories.

In addition, interactive API documentation is automatically generated from our OpenAPI spec.
