Tantivy is great! I was using Postgres FTS with trigrams to index a few hundred thousand address strings for a project of mine [0], but this didn’t scale as well as I’d hoped with a couple million addresses. Replaced it with the tantivy cli [1] and it works a charm (ms searches on a single core vm).
