Yes :) Valerian Saliou, the maintainer of Sonic is a friend of us. He built Sonic mainly for his company (crisp.chat) and compared to MeiliSearch there is no relevancy ranking.

Sonic is "just" a inverted index with a levenshtein automaton, it will returns only the documents ids in which there is your requests words and then you will have to retrieve the full documents in your main database and only then can you apply some relevancy ranking by yourself.
