@AliceCheshire I do know that the old functionality was flawed and needed replacing. It didn't actually look for authors, just the text string. They've wanted to replace it so that you can actually find the works by the same author when their contracts demand either a reversed name order or different spelling to another work they already have. Like The Magic in this Other World is Too Far Behind! vs The Magician Who Rose From Failure
Also caused problems when someone's penname was a smaller portion of another's name (Black Summoner's illustrator Kurogin vs Haibara's Teenage New Game+'s illustrator Gin).
Unsure why the replacement isn't yet in place, but it did at least need one.
