I have a lot of questions.  For example, the javadocs for the "KeywordField" 
class says: "... doc values for sorting and faceting"

Yet, I don't see a way with 9.8.x Lucene to perform faceting on fields that 
haven't been specifically indexed for faceting.  I clearly need a lesson or two 
on faceting in Lucene.  I don't understand what a "path" is for example.  Of 
course I have tried to work with the examples, but unless I completely rework 
my indexes, I'm stuck.  I thought you could use DocValues somehow to facilitate 
faceting queries.  Anyway, I suppose I'll need to use the source code as my 
guide and spend a lot of time working with it.  I was hoping to find some 
really good documentation to help me cut to the chase.  I appreciate you 
offering to help answer any questions, seems like I could use an interactive 
session 😊

Hi Tony,

Have you looked at the faceting demo package [1]?

The faceting documentation that lives there [2] was updated last year (thanks
@epotyom!) and there haven't been major API changes since.

The `SimpleSortedSetFacetsExample` [3] might be a good starting point for what 
you're trying to do.

If you've already checked these resources, is there a specific question they 
didn't help answer?
