When on the search tab of the Autodesk Simulation Mechanical Help, it is possible to choose from certain areas to search in for returns of topics. The current list is; Everywhere, Getting Started, Learn & Explore, Downloads, Troubleshooting and Installation & Deployment. I would like to be able to narrow this search only to the core documentation written for the software. I would like this pull down list needs to have an option for "User's Guide" only.
