Is it possible to change what fields appear in the document summary? I would like for only the raise user to appear in this section. No matter what i seem to do it also includes the title and description.
Yes it is...Under Knowledge Managment Administration > Configuration:
Double click on the appropriate module and business object and you should see the attributes for that object. Scroll towards the bottome of the list of attributes, and you should see where the "Search Layout" is. You can add attributes by right-clicking on them and choosing "add to search layout", or remove them by chooisng "delete attribute". The screenshot attached will point you in the right direction.
