"Long story short: Meilisearch is a very good search application for sure, but our needs drifted apart. [...] Our usecase isn't entirely aligned with how Meilisearch is meant to be used, I think. For one, we have a very high number of indices [...] In the end I was ending up spending an inordinate amount of time wrangling Meilisearch to get indices up and running across our different edge nodes [...] the amount of effort needed to orchestrate and keep all the individual Meilisearch nodes up to date and in sync just turned out to be too much hassle."
