Another thing I wanted to mention about this post topic and the FBI Vault, is they don't show you it in the index as a "popular" thing to look into https://vault.fbi.gov/reading-room-index
This reduces visiblity, as you won't be browsing it form the index and won't know about it as a topic there. It hides it. I suspect they have moreseriously damning topics like Op Condor missing in the index.
For sure, I do not like the Vault search. It does seem to be poorly designed. I found the Condor docs from the recent archive dump at intel.gov. I dunno if I would have found it if not for the recent release.
Also, I wouldn't doubt it if this was done intentionally if they indeed wanted to make it difficult to find more significant documents. I completely agree, the 'popular' section is full of celebrity names and reports and does not highlight anything particularly interesting.
