What are conditions to unlock artifacts sets in Archive?

I noticed this from my 3* Gambler Set that i used up earlier, You only need to collect them once.

for example: if you previously collected a feather artifact and used it to levelling-up another artifact and then you get the other 4 artifact types from the same set and same rank in the future, it will show you the artifact set from the archive because you completed collecting 5 artifact from each different type within the same set and same rank.
