- Make scanned document searchable
Copy link to clipboard
Sometimes when searching for documents online I come across a scanned document, maybe a historic or hand written document hundreds of years old, but the search has found the text I was looking for in the document, and the page it is on. There is often a menu saying how many times this text appears in the document, and allowing me to move quickly backwards and forward between these.
It seems like the document contains the images of the original pages, but also the OCR'd text, and somehow each word of OCR'd text knows which part of the original image it came from, because when you search for a word it finds it, and highlights it in the original scanned document.
I now have photocopies of a lot of historic documents (they are letters written by my gt gt grandfather) which I would like to do this with. I would like the text to be searchable, but I would like the original images of the pages there, and for the found words to be highlighted in the original images.
Can this be done? How?
What software do I need to do this?
Does PDF have the ability to store the images and the text and the relationship between the two to enable this? If not, what format does allow this?
