THEN Change the `delete_doc_id` method to use OpenSearch's `delete_by_query` to match on the stored `doc_id` field instead of the auto-generated document ID. If the backend (e.g., AOSS) does not support `delete_by_query`, implement a workaround like fetching the document first and then deleting by its `_id`.

def delete_doc_id(self, doc_id: str) -> None:
    # Use delete_by_query to delete documents with matching doc_id
    self._os_client.delete_by_query(
        index=self._index,
        body={"query": {"term": {"doc_id": doc_id}}},
        refresh=True
    )
