wado-rs /metadata can I filter fields ? Maybe with includefield ?

[julien-louis]

Hi I do this kind of requests :

http://dcm4chee-arc:8081/dcm4chee-arc/aets/AS_RECEIVED/rs/studies/1.4.9.12.34.1.8527.3205015702217000097176372938058190999089/series/1.4.9.12.34.1.8527.3127298143853961430167573315057188439826/instances/1.4.9.12.34.1.8527.4046386518804406242396726261157005204749/metadata/

and I would like to filter the metadata retrieved, maybe like that :

http://dcm4chee-arc:8081/dcm4chee-arc/aets/AS_RECEIVED/rs/studies/1.4.9.12.34.1.8527.3205015702217000097176372938058190999089/series/1.4.9.12.34.1.8527.3127298143853961430167573315057188439826/instances/1.4.9.12.34.1.8527.4046386518804406242396726261157005204749/metadata?includefield=1572993

but it does't seem to work. I do that because some issues I found here suggest that it is supported.

What do I do wrong ?
