Final answer:
To include a new HR Knowledge base in search results on an HR Case form, it is usually included by default, but you might need to add it to the Contextual Search configuration if necessary.
Step-by-step explanation:
To include a new HR Knowledge base in the Knowledge results section on the HR Case form, the correct action to take depends on the specific configuration of the tool used for managing HR cases. If the tool is a software like ServiceNow that provides HR service delivery, there are specific steps to configure the knowledge bases.
Option 3, "All Knowledge bases are searched by default," is the likely default setting in many systems, including ServiceNow. This means that when a new Knowledge base is created, it is automatically made searchable and can appear in the Knowledge results, provided that the user's role has the necessary permissions to access it.
However, it could also sometimes be necessary to specifically include the new Knowledge base in the search results. This might involve configuring the Contextual Search settings to make sure that the new knowledge base is part of the search context. Option 4, "Add it to the Contextual Search configuration," would be the right step in this scenario.
It is less likely that adding the new knowledge base to a template (option 1) or an HR service configuration (option 2) would be required to make the knowledge base searchable in the case records, as these actions relate to different aspects of setting up HR services and forms.
