I have a pile of part lists for tools I’m maintaining, in pdf format; and I’m looking for a good way to take a part number, search through the collection of pdfs, and output which files contain that number. Essentially letting me match random unknown part numbers to a tool in our fleet.
I’m pretty sure the majority of them are actual text you can select and copy+paste, so searching those shouldn’t be too difficult; but I do know there’s at least a couple in there that are just a string of jpgs packed in a pdf file. They will probably need OCR, but tbh I can probably live with skipping over those altogether.
I’ve been thinking of spinning up an instance of paperless-ngx and stuffing them all in there so I can let it index the contents including using OCR, then use it’s search feature; but that also seems a tad overkill.
I’m wondering if you fine folks have any better ideas. What do you think?
In case you are already using ripgrep (rg) instead of grep, there is also ripgrep-all (rga) which lets you search through a whole bunch of files like PDFs quickly. And it’s cached, so while the first indexing takes a moment any further search is lightning fast.
It supports a whole truckload of file types (pdf, odt, xlsx, tar.gz, mp4, and so on) but i mostly used it to quickly search through thousands of research papers. Takes around 5 minutes to index everything for my 4000 PDFs on the first run, then it’s smooth sailing for any further searches from there.
