Reload deleted feed entries

Hi,

I am new to DEVONthink Pro and I am still playing with it. In this experimental phase, I have added a couple of feeds and read the entries. Sadly at a given point I have deleted some of the entries and emptied the trashcan ¬¬ I would like to know if there is any possibility to reload a feed (even if you have deleted the entries).

Thank you for your time
