Reading from a Text and Scanned pdf and then perform a search on them

Hi,

Just introduced to the KNIME world and have been mesmerized about it.

Now, I am planning to create an Analytics with couple of PDF files, some of them are scanned pdf, I need to perform the following.

  1. Search availability of a text string in those PDF files.

  2. Filter the pdfs which contain that string.

  3. Highlight the related section or text , which contains the string.

Could you kindly help me building a model to perform this?

Thanks,

Rajib
