I don't think he misunderstood anything. There's the kind of library Lucene wants to be, a configurable library. But there are other libraries do not want that. In this case, Datalevin is a database system, full-text search is just but a feature, I do not want users to configure full-text search in Datalevin as much as they like in Lucene. I want the default to be good, which Lucene's is not.
