With the recent introduction of Machine Learning in Google Drive, your search for the right document just got faster. Using the OCR tool, it also searches for text inside the images and PDF files. Whether it’s a keyword you remembered or a certain date range, you get intuitive results. Google Drive has an advanced search feature that quickly leads you to the exact document. Just remember to convert from clear, high-resolution images containing a normal typeface such as Arial or Verdana. This feature is really helpful if you have a write-protected PDF file or a book’s scanned pages.
