Can not filter RQM test steps with OSLC.WHERE by title

Hello!

I'm using Postman to get test execution steps from Rational Quality Manager v6.0.4. I do GET request with next URI:

https://jazz.server.com:9443/qm/oslc_qm/contexts/_S27gMLfpEeeEgs7LYGmNuA/resources/com.ibm.rqm.planning.ExecutionElement2?oslc.properties=dcterms:title

It works perfect! I have a response:

Next, I want filter the response by title. But if I use next URI:

https://jazz.server.com:9443/qm/oslc_qm/contexts/_S27gMLfpEeeEgs7LYGmNuA/resources/com.ibm.rqm.planning.ExecutionElement2?oslc.properties=dcterms:title&oslc.where=dcterms:title=%22111%22

And I have an error in the response:
