Hi nerds, Ever feel like Zebra is an intimidating black box of mystery? Well, you're certainly not alone. That's how I felt when I first encountered it over 10 years ago. Over the past decade, I've read through the C code and submitted issue reports to Indexdata, but it wasn't until the other day that I decided I'd try hacking on Zebra to try to understand its operation better (especially faceting). I kept notes of my process for developing and testing Zebra and I've posted them to https://wiki.koha-community.org/wiki/Developing_Zebra. Using these straightforward steps you should be able to hack, compile, and run Zebra. (At some stage, I might actually provide a Dockerfile or Docker image that is even more convenient.) When looking at faceting, I wasn't able to solve the problem, but I was able to isolate the problematic function by hacking on Zebra, and now I'm waiting to hear back from Indexdata for advice. So I think it was a useful exercise. I think Tomas has already hacked on Zebra, so he probably doesn't need this, but I thought it might be interesting for people to review and try if they were interested.
