I am on macOS Tahoe 6.10. The AI powered natural language intelligence search that's supposed to be built into the current version of macOS and Photos doesn't work for me. For example, if I type "black shirt" it shows nothing (I have several photos with people in black t-shirts, shirts or tops - or "London 2023" (it shows a jumble of photos from various trips to London - not just 2023 and not all). In the window that opens below the search bar, it always says Indexing... but this has not changed for the past 2-3 weeks. How to fix?
