+## Filter list of registry records

+```{versionadded} plone.restapi 9.10.0
+```
+
+You can filter a list of registry records and batch the results.
+To do so, append a query string to the listing endpoint with a `q` parameter and its value set to the prefix of the desired record name.
+See {doc}`../usage/batching` for details of how to work with batched results.
