Hello, I'm currently using FTS4 and would like to use FTS5 to take advantage of its partial matching ability. With FTS4 I use the `offsets` function to locate the exact position in the source documents. But since FTS5 has no such function, I'd like to ask: - I read from the SQLite document that the `offsets` function might be added in the future, so what's the estimated time frame, if any? - Anyone can point me to any custom `offsets` implementations for FTS5 so that i can port it to my language? Take care and Thanks!
