Problem with Finder search after upgrading to Cataline

I upgraded to Catalina on my MBP Retina 13"(Late 2013) recently. It was fine till a few days. The issue likely started after the last update: When searching by name for files in Folder through search, nothing shows up(like it used to do before) and just keeps "loading". When I do the same search in Spotlight, all the files are shown, but when I opt for "show all in finder" at the bottom, the same "loading" starts. It is really creating a problem as I use this search a lot to track files with similar names. Earlier, everything on my Mac used to show up in a jiffy. At first I panicked thinking that files had disappeared or that I had been hacked! But I find that the files are very much there, but just not getting found ! Please help
