Detect duplicate article in different feed

[cloutierjo]

I have many feed from the same editor and they often publish the same article in more than one feed. It would be great if that article where shown only once in the aggregated view (those that show more than one feed) and if it is marked as read in any way that all reference to this article be marked as read.

Exemple feed (can’t guarantee they will have duplicate at all time, but those often does): https://ici.radio-canada.ca/rss/4159 https://ici.radio-canada.ca/rss/1000524
