[generall]

The latency of the combination of parallel systems is equal to the slowest component. And obviously, specialized tools will be faster than a component of a multi-tool system cause while dedicated engines can invest in optimizing specific functionality, multi-tool engines are stuck in the integration hell.

A solution assembled for a specific task from highly specialized components will always be more optimal than 'one-size-fits-all' pipelines. Meilisearch solves search-as-you-type better than anyone else, so why compromise? Not to mention that the scalability pattern of BM25 and vector search is entirely different.

This, by the way, is pretty obvious from the fact that you don't publish comparative benchmarks.
