Searching through physical documents
Searching through a digital document is easy these days: in an e-mail, Word file or a PDF document you can look for keywords using the program’s built-in search function. It’s more difficult to find specific text in a physical document. The Android app Find It ( https://devpost.com/software/find-it-real-time-document-search ) can help you - it can find (multiple) search terms in a text via your smartphone camera. Just type your query and point your camera at a document - the words found will be highlighted in yellow.
