The new Catalog Lookup in AutoCAD Electrical 2011 allows you to filter and search by any field, Manufacturer, Type, Style etc. However there is a large performance overhead with this, so the Catalog Lookup is pre-filtered on opening to prevent all the records having to be loaded (the pushbutton component table has just under 100000 records for example). If you are editing the component and it already has Catalog information applied then it will filter using this information. It will filter on the Manufacturer and the fourth and fifth fields in the table (which are different for each component type).
