How do I get the detailed description for a board?

In the Community Admin, you can create a title, short title, description, detailed description, etc...  The API documentation shows that you can display the title, description, etc... but doesn't say anything about the detailed description.   Is it possible to do this, or is this a missing piece in the API?

Here is the code that works to display the description.

<#assign page_info = rest("2.0","/search?q=" + "SELECT id, title, description FROM boards WHERE id = '${coreNode.id}'"?url).data.items />

${page_info[0].description}
