Now, on completing project, the Q&As are moved to Content library with tags, author, project name and other details. But project type is not directly associated with project Q&As and they are not migrated to CL.
So there is no way to filter the Q&As based on project type in the CL. So, on indexing the project Q&As to CL, the project type should also be migrated to CL similar to project name for better grouping and filtering capabilities.
