Salesforce has a rudimentary indexing tool when files are uploaded. If there is a rendered or created PDF or a word document then all of the text can be indexed and searched. However, if I upload a scanned documented of a PDF or a TIFF/jpg then I lose that indexing functionality.
I've been looking for OCR solutions. Most don't seem to index but they do read fields and upsert records. Is there an OCR document indexing app?
