Me too! That's why it's very important when you say things like that to make sure you provide enough evidences. In this case there is https://db-benchmarks.com/ where you can see all the details and it's 100% opensource - https://github.com/db-benchmarks/db-benchmarks including the UI https://github.com/db-benchmarks/ui . The results themselves are opensource too - https://github.com/db-benchmarks/db-benchmarks/tree/main/res...
So anyone can reproduce the results or at least look carefully into them, understand the testing methodology etc.

They released an official C# client few weeks ago. Nice.

A Heterogeneous Benchmark for Information Retrieval. Easy to use, evaluate your models across 15+ diverse IR datasets.
True! Here's a pull request to BEIR to compare Manticore with Elasticsearch in terms of relevance https://github.com/beir-cellar/beir/pull/92. Spoiler: in this test Manticore provides better relevance than Elasticsearch in average. Of course you can tune both further and Elasticsearch now has KNN which when combined with BM25 can give even better relevance. In general I would say for most users the results quality in terms of full-text relevance is about the same in Elasticseach and Manticore.
