A little bit tough to get it started, but once I did I really liked the final results. There is a ridiculous amount of power in this that you can use if you want to (but pay for it). This is close to enterprise level search for a reasonable price per month.
We removed Algolia because the free 10k operations don't last long at all. This includes all indexing, searching (per key), etc. If they had a cheaper intro plan we'd probably jump in, but I'll look around to see if there's another option at the price point we need.
