is faceted search currently available? otherwise will faceted search be part of the dev roadmap?

There is no support for that, at least not out of the box. You can certainly build multiple indices and then write some code to organize it into a single faceted system. But then there's no mechanism to, say, parse a complex query using multiple indices, or anything like that.

This is not a very technically difficult thing to implement in PISA, but the way everything is currently designed, it needs some care to come up with a sensible way to introduce it.

I would love to work on that, but not able to commit to anything. We have very limited resources, and there's no clear roadmap. I'm currently trying to close some issues, but mostly low hanging fruits at the moment.
