block keyword behaviour is changed when site is specified

[tvami]

When block dataset=/SingleMuon/Run2018C-15Feb2022_UL2018-v1/AOD site=T2_RU_JINR
https://cmsweb.cern.ch/das/request?view=list&limit=50&instance=prod%2Fglobal&input=block+dataset%3D%2FSingleMuon%2FRun2018C-15Feb2022_UL2018-v1%2FAOD+site%3DT2_RU_JINR
that seems to return files (which are I understand "blocks" in Rucio language) while w/o the site requirement it returns "blocks"
https://cmsweb.cern.ch/das/request?view=list&limit=50&instance=prod%2Fglobal&input=block+dataset%3D%2FSingleMuon%2FRun2018C-15Feb2022_UL2018-v1%2FAOD with the DBS meaning of a "block".

Also when asking for files with the site requirement I get a single "file"
https://cmsweb.cern.ch/das/request?view=list&limit=50&instance=prod%2Fglobal&input=file+dataset%3D%2FSingleMuon%2FRun2018C-15Feb2022_UL2018-v1%2FAOD+site%3DT2_RU_JINR
while I got 4372 "block"s in the first link. I'll check if the same is true in the terminal command.

I'll check if the same is true in the terminal command.

I did

dasgoclient --query="block dataset=/SingleMuon/Run2018C-15Feb2022_UL2018-v1/AOD site=T2_RU_JINR"

it returns a long list of files, identical to the browser results.
