:not query operator not working in Cerner

[Winston Leung]

Hello,

I'm looking to be able to query all observations of a patient that do not fall under the vital signs category. The search I am using for this is "[base]/Observation?category:not=vital-signs&subject=Patient/[id]."

This gives me a 400 error. I figured the :not is the reason for failure because without it the search goes through.

Tested the same query in the SMART app launcher and it works as well.

Thanks for the help.

Hello,

:not is not a modifier we support.
