Search function not finding clips in Premiere Pro

I'm finding that I cannot reliably find clips in the search bars in Premiere Pro.  I thought this was because I was a newbie, but then I found this post from December 15, 2018 ("Premiere Pro CC 2019 13.0.2 search/find/bin filter issues") by a user named jblaz, who wrote:

"I started having issues with the project panel bin filter search not showing clips that I knew were in the project - I'd search for a word in the name of a clip and no clips would show up."

That is the same problem I seem to be having.  Case in point:

I created a video clip that I know is entitled comedian1_4.avi.  I know this because that's what I see as the file name when I export it.  It even shows that it's in the comedian1 folder.

But when I search for the word "comedian" in the bin folders, there are no hits.  Nor do I see the comedian1_4.avi file in any bin nor after searching in the media browser.

The tutorials I watched suggested that the clips I created would appear in the bin from which I was working, but that is not happening for me.  Nor can I find the clips anywhere else.  They eventually seem to pop up without rhyme or reason.  I'm wondering if it's a filter issue of some kind.

There's always the possibility that I'm "missing something" as a newbie, but I have watched dozens of videos and I am still puzzled by the apparent inability of the search function to reliably find the clips that I'm creating.
