Search not working-Sequoia 15.1 Update

Good morning. Is it? Today's daily issue: Search is not working after the Sequoia 15.1 update. I used "This Mac," Name contains "......", Everything "....."

I also tested it by pasting in a file name I had copied from a folder and no go. Oh yeah! Usually, files come up that do not correlate with the search wording! By the way, this is an annoyance occurring in previous MacOS's. How do you stop it?? I must delete a letter and type it back in to get Name Contains "....."

Research tells me I have to re-index Spotlight. Why do I have to do this? Isn't an update supposed to make things easier and better? And how does a true Mac user re-index anything- it used to be readily available?

Please help! Search is a vital function.
