Similar exp lol. I was instantly sold at the ease of installation, great documentation, and the built-in search interface web app.
Had to put it on the side for a while when I noticed it just indexed 3m docs in 8hrs (compared to 70m docs in 8 hrs of same data on elasticsearch). There were tips given on their slack but we found it a bit too hacky (at that moment) for our use case (you know, worries that will such approach be consistent or broken on next versions, things like that).
Nevertheless I still think it's perfect for hundreds of thousands of documents at the moment (just not millions yet).
