I tried this but doesn’t return anything, If i try something like patientID, studyID or Physician name it returns the result-set.

```auto
curl --request POST --url [http://localhost:8042/tools/find](http://localhost:8042/tools/find) --data '{"Level":"Instance","Query":{"0008,0100":"test"}}'

```

Are you actually sure that you have data with these tags ?

I don’t → I get no results

$ curl --request POST --url [http://localhost:8042/tools/find](http://localhost:8042/tools/find) --data ‘{“Level”:“Study”,“Query”:{“0008,0100”:“\*”}}’  
[]

when trying any other fancy tag that are present in at least one image → I get results:  
$ curl --request POST --url [http://localhost:8042/tools/find](http://localhost:8042/tools/find) --data ‘{“Level”:“Study”,“Query”:{“0028,1101”:“\*”}}’

small question about that,  
is it possible to search for a metadata value using this /tool/find API ?
