What to do with documents without a description

[siccovansas]

Some documents don't have a description, e.g.: https://api.poliflw.nl/v0/combined_index/1a466b696c8f6861498faff10897cb9c7c011b7f

Why is this? If you go to the source of that document you see that there actually is text available. Did the parsing fail? Was there no text when we scraped it?

What should we do when we end up with no text for a document. Keep it for completeness sake (and users can check the source themselves), or don't save the document at all?
