Keyword search fails to return results in Photos
I want to search in Photos for those photos with a particular keyword. No matter which keyword I choose I get zero results from that keyword. E.g. I have dozens of photos with the keyword "Food". I type Food into the search box and I get ZERO results with that keyword. So one by one I try typing a keyword into the search box. Not one keyword returns a result. What gives?
I've got a mid 2011 iMac. I recently upgraded to High Sierra (10.13.3). Sorry, I can't say if this problem existed before the upgrade or not. I've got more that 21,000 photos in Photos. I do NOT store my photos in the cloud; they are on the iMac.
I'd appreciate some help on this one.
Thanks!
iMac (27-inch Mid 2011), iOS 11.0.3
