finding the file that contains a run,lumi is not working about das HOT 6 CLOSED

Andrew,
I don't think I support file dataset=/a/b/c run=XXX lumi=ZZZ syntax, instead you should query
file,run,lumi dataset=/ZGToLLG_01J_5f_TuneCUETP8M1_13TeV-amcatnloFXFX-pythia8/RunIISummer16MiniAODv2-PUMoriond17_80X_mcRun2_asymptotic_2016_TrancheIV_v6-v1/MINIAODSIM
which provides results, see
https://cmsweb.cern.ch/das/request?view=list&limit=50&instance=prod%2Fglobal&input=file%2Crun%2Clumi+dataset%3D%2FZGToLLG_01J_5f_TuneCUETP8M1_13TeV-amcatnloFXFX-pythia8%2FRunIISummer16MiniAODv2-PUMoriond17_80X_mcRun2_asymptotic_2016_TrancheIV_v6-v1%2FMINIAODSIM

from das.

If you use dasgoclient you can see all supported queries/synyax as easy as
dasgoclient -examples

from das.

ok, but this query definitely used to work

if the query is not supported, shouldn't there be an error instead of just returning "No results found"?

from das.

Andrew, you're right this query syntax is supported (sorry I'm in C&O week with plenty of tasks and multitasking leads to gap in my head).

But upon further investigation it seems that the problem is with DBS, see yourself:

dasgoclient -query="file dataset=/ZGToLLG_01J_5f_TuneCUETP8M1_13TeV-amcatnloFXFX-pythia8/RunIISummer16MiniAODv2-PUMoriond17_80X_mcRun2_asymptotic_2016_TrancheIV_v6-v1/MINIAODSIM run=1 lumi=1" --verbose 3

will return series of URL calls to DBS, like this

 https://cmsweb.cern.ch/dbs/prod/global/DBSReader/filelumis?block_name=%2FZGToLLG_01J_5f_TuneCUETP8M1_13TeV-amcatnloFXFX-pythia8%2FRunIISummer16MiniAODv2-PUMoriond17_80X_mcRun2_asymptotic_2016_TrancheIV_v6-v1%2FMINIAODSIM%23a712e608-0775-11e8-a129-02163e01877e&run_num=1

which by itself returns

{"exception": 500, "type": "dbsException", "message": "Server Error"}

So, we need Yuyi (@yuyiguo) to provide more info on why DBS queries are failing.

Hi Andrew, Valentin:
This listFileLumis API support run_num input, but run_num is not 1. Please see the doc below:
https://cms-http-group.web.cern.ch/cms-http-group/apidoc/dbs3-client/current/dbs.apis.html?highlight=listfilelumi#dbs.apis.dbsClient.DbsApi.listFileLumis

the same API called w/o run_num=1:

I opened a issue to fix the problem: dmwm/DBS#587.

Thanks for reporting the issue. Just a reminder that most DBS APIs do not support run_num=1 search.

I"m not sure that it still valid issue. If so I suggest to open new issue with new information. So far I'm closing this now.
