I'm looking for some kind of (free or open source) document management application which should allow me to store paper documents in my personal computer allowing me to add fields of information with data entry to be able to get the digital copy back.

For example, if the document is a fine I can find it if I remember the date or the fact that is a fine or another custom field I could add to search.

OCR full text search would be a great plus but not mandatory.
