    def delete(self, ids: list[str] | None = None, **kwargs: Any) -> DeleteResponse:
        """Delete by IDs or other criteria.

        Calling delete without any input parameters should raise a ValueError!

        Args:
            ids: List of IDs to delete.
            **kwargs: Additional keyword arguments. This is up to the implementation.
                For example, can include an option to delete the entire index,
                or else issue a non-blocking delete etc.

        Returns:
            A response object that contains the list of IDs that were
            successfully deleted and the list of IDs that failed to be deleted.
