+    """
+    Return all elements from the given list that match the selection criteria.
+
+    You can provide name or ID and all matching elements will be returned.
+    If both name and ID are given, elements matching either criterion will be
+    returned.
+
+    If an Entity is given, neither name nor ID may be set. In this case, only
+    elements matching both name and ID of the Entity are returned, as long as
+    name and ID are both set.
+
+    In case the elements contained in the given list are wrapped, the function
+    in its default configuration checks both the wrapped and wrapper Entity
+    against the match criteria, and will return the wrapped Entity if both
+    match. Note that this is currently not iterative, meaning that only the
+    first layer of wrapped entity is considered.
