The ability to do a search for components from the Object Browser is a helpful feature new to SAP BusinessObjects Dashboards 4.1. You can perform a search by either name or component type. This comes in handy when you have a lot of objects on the dashboard that are inside groups or canvas containers.
Open up the Object Browser window.
In the top-left input box, type in the object name or component type that you are searching for. You will see that your search will filter the objects accordingly.
