@@ -614,9 +614,10 @@ Spring Session's most basic API for using a `Session` is the `SessionRepository`
 This API is intentionally very simple, so that it is easy to provide additional implementations with basic functionality.
 
 Some `SessionRepository` implementations may choose to implement `FindByIndexNameSessionRepository` also.
-For example, Spring's Redis support implements `FindByIndexNameSessionRepository`.
+For example, Spring's Redis, JDBC and Hazelcast support all implement `FindByIndexNameSessionRepository`.
 
-The `FindByIndexNameSessionRepository` adds a single method to look up all the sessions for a particular user.
+The `FindByIndexNameSessionRepository` provides a method to look up all the sessions with a given index name and index value.
+As a common use case that is supported by all provided `FindByIndexNameSessionRepository` implementations, there's a convenient method to look up all the sessions for a particular user.
 This is done by ensuring that the session attribute with the name `FindByIndexNameSessionRepository.PRINCIPAL_NAME_INDEX_NAME` is populated with the username.
 It is the responsibility of the developer to ensure the attribute is populated since Spring Session is not aware of the authentication mechanism being used.
 An example of how this might be used can be seen below:
