We are seeing the increasing need to add data fields to an indexed dataset. An example would be if I come across a document called 'Untitled.pdf' and the date 01/01/2000. After review, the document is called 'Joe Blogs Report' and the date on the document is correct, is there a way to create an extra field to add to the data set and be able to search for the correct information. I thought the overlay file would allow the function to add columns of data but from what I can see this only transfer tags between cases.
