Ask HN: Tool to auto-index any file and its content

I recently discovered PhotoPrism[0] which does a great job at indexing photos and videos we throw at it.

My setup is Docker on a Synology NAS.

I would like to find a self-hosted tool to basically throw any kind of files (.txt, .zip, .docx, .pdf), sort it automatically by dates, manages duplicates for me and, ideally, index their content for text-based files.

IndexYourFiles[1] seems to do that, but they distribute desktop app and seem closed source.

Any recommendation?
