I'm following the video tutorial below, using the exact examples, but was not able to semantically match the results: https://developer.apple.com/videos/play/wwdc2024/10131 https://developer.apple.com/documentation/corespotlight/building-a-search-interface-for-your-app In iOS 18 and macOS 15 and later, Spotlight also supports semantic searches of your content, in addition to lexical matching of a search term. I'm on macOS 15.1, so I'd expect it should work now? Or is this depend on Apple Intelligence for some reason? Specifically I've indexed the following: Keyword: "windsurfing carmel" Literal match: the best windsurfing carmel county windsurfing lessons Semantic match: sailboarding lessons the best windsurfing carmel county windsurfing lessons Expected: find semantic match. Actual: only literal match were returned. Because CSUserQuery.prepare is only supported by macOS 15, my switch from CSSearchQuery makes no sense without the semantic search benefits. Did I miss something? I also added the corespotlight delegate extension as directed but was not able to hit the breakpoint as per the video. I wish there is the sample code for this, but couldn't find it.
