[web-api]Support for ! operator in trackedEntityInstances parameters?

Support - Assistance technique

Hi All

I am trying to get all the TEIs which are not of a particular tracked entity. I tried with the ! operator but i don’t think that this works.

Here is a template request I used to test on the dev server - [ https://apps.dhis2.org/dev/api/trackedEntityInstances.json?ou=DiszpKrYNg8&ouMode=SELECTED&trackedEntity!=cyl5vuJ5ETQ&pageSize=50&page=1&totalPages=true ]

Now I am changing my approach and filtering the data after it is fetched. But just to get this confirmed I am asking this question -

Is there a way by which I can do this with the Web API directly?

Thank You
