-        Find indices of devices that satisfy the given `key=value` condition.
-
-        This method iterates over all models in this group.
-
-        .. note::
-            New in version 0.9.14. Duplicate of `andes.models.group.GroupBase.find_idx`.
-
-        Parameters
-        ----------
-        keys : str, array-like, Sized
-            A string or an array-like of strings containing the names of parameters for the search criteria.
-        values : array, array of arrays, Sized
-            Values for the corresponding key to search for. If keys is a str, values should be an array of
-            elements. If keys is a list, values should be an array of arrays, each corresponding to the key.
-        allow_none : bool, optional
-            Allow key, value to be not found. Used by groups. Default is False.
-        default : bool, optional
-            Default idx to return if not found (missing). Default is None.
-        allow_all : bool, optional
-            Return all matches if set to True. Default is False.
-
-        Returns
-        -------
-        list
-            Indices of devices.
