I tried both Mayan and Paperless (regular) myself to replace my Evernote Premium setup, they haven't convinced me yet.
I am currently trying out https://github.com/jbarlow83/OCRmyPDF myself (had to fork it to add my own language to the Dockerfile) and then will either let my NAS index it afterwards or Dropbox/Nextcloud maybe. Apparently locally they get indexed very well with either Gnome (Linux) or Finder (Mac) or Explorer (Windows).
