Multiple word search not working using desktop app

Multiple word search not working using desktop app

Recently multiple word searches have stopped working using the Zoho Notebook desktop app on my 2 computers running Windows 10. Single word searches work fine, but as soon as add a second word, I get the "Search for" prompt and if I select it, I get "No result found". This happens even when the search words are consecutive in a note title or body of a note. Multiple word searches work fine if I log into Notebook in  a browser (Chrome) on the same computers or using the Notebook app on my phone or tablet. I tried reinstalling the desktop app on one of the computers, but that didn't make any difference.
