 If the server generates any link:{neo4j-docs-base-uri}/status-codes/current/notifications[notifications], they will be returned in the `notifications` key of the response object (as a list).
 Notifications include recommendations for performance improvements, warnings about the usage of deprecated features, and other hints about sub-optimal usage of Neo4j.
 
+[NOTE]
+If the server generates an unsupported notification category, the Query API will omit the category field.

+[#filter-notifications]
+=== Filter notifications
+
+By default, the server analyses each query for all categories and severity of notifications. Use the parameters `minimumSeverityLevel` and/or `disabledCategories` to restrict the severity and/or category of notifications that you are interested into. There is a slight performance gain in restricting the amount of notifications the server is allowed to raise. You can use any of those parameters either when running a single query or while begin a transaction.
+
+The filter can be configured trough the optional `notificationsFilter`. This is an object which can contain the following properties: 
+
+* `minimumSeverityLevel` (optional) - Defines the minimum severity level . Possible values: `WARNING``, `INFORMATION` and `OFF`.
+* `disabledCategories` (optional) - Defines the list of categories disabled to be returned. Possible values on the list:  `HINT`, `UNRECOGNIZED`, `UNSUPPORTED`,  `PERFORMANCE`,  `TOPOLOGY`,  `SECURITY`,  `DEPRECATION`,  `GENERIC`  and `SCHEMA`
