CCM rest API: How to make a query with multiple filters?

Hi,

i am currently trying to get wokItems from a specific project filtered by different status. For exemple i want the workitems in the project 1 that are closed or resolved.

For this i am making this query:

https://<localhost>/ccm/rpt/repository/workitem?fields=workitem/workItem[projectArea/name="project1" and state/id=de.ohb.team.workitem.workflow.task.1.state.s4 or state/id=de.ohb.team.workitem.workflow.task.1.state.s3]/(summary|id|severity/name|state/name|state/id|priority/name|itemHistory/modified|itemHistory/priority/|itemHistory/severity/|itemHistory/state/*)

I think the issue is that this query will give me results that are like this:
workItems from project1 that have the statu 4
OR
workItems that have the statu 3

Can you please tell me what i am doing wrong ?
Thank you
