Description of the problem including expected versus actual behavior:
The Security rule creation UI allows you to create a rule based on index patterns or data views. Confusingly, Elastic has two different things called "index pattern": an Elasticsearch construct, and a Kibana construct (deprecated, now called "data view"). I think the link for "index patterns" (see red arrow in the screenshot) goes to the wrong docs. It points to API docs for the deprecated Kibana construct, but it should point to the ES construct.
Kibana version: 8.9

I think a better page to link to could be https://www.elastic.co/guide/en/elasticsearch/reference/current/api-conventions.html#api-multi-index, or even better a new standalone page that explains what index patterns are in this context.
