That documentation is helpful, not quite what I was looking for though. Essentially I was going to use HubL to display a series of posts based on a specific combination of tags only if they were both mutually present at the same time.
Said another way, instead of getting all posts tagged with either topic1 and or topic2, only show posts when topic1 and topic2 exist together.
I ended up using some filtering, post IDs and a drop down to select specific posts to show where relevant. This was for a directory listing, not a traditional blog if curious.
