Context: my father is a lawyer and therefore has a bajillion pdf files that were digitised, stored in a server. I’ve gotten an idea on how to do OCR in all of them.
But after that, how can I make them easily searchable? (Keep in mind that unfortunately, the directory structure is important information to classify the files, aka you may have a path like clientABC/caseAV1/d.pdf
What’s a bajillion? If the OCR output is less than a few GB, which is a heck of a lot of text (like a million pages), just grepping the files is not too bad. Maybe a second or two. Otherwise you need search software. solr.apache.org is what I’m used to but there are tons of options.
