tracker search --folders <expression> returns no results

Starting with Fedora 32, the file chooser search feature doesn't work at all for me. It finds things in the current directory but not in subdirectories. I think this is caused by tracker folder search being very broken. For example:

$ tracker search --folders |grep Receipts
  file:///home/luto/Documents/AdHoc/Receipts

NOTE: Limit was reached, there are more items in the database not listed here
$ tracker search --folders Receipts
Files:

I have not been able to find any nonempty search expressions at all that cause tracker search to return any results at all. (I also can't get search for things other than folders to work, but I care more about folders.)
