How is Kentico smart search relevance score determined? I've had a client ask me this and after a bit of research I can't find much answers.
There isn't a simple answer to your question. Under the hood Kentico uses Lucene or Azure Search indexes, depending on your version and configuration. You can find out how score is calculated for Lucene indexes here.
You can check more details here. But you can also boost some fields and change the search fields settings, analyzer type, add search conditions etc to manipulate how the results list will look like.
