Remarks
The component filters may be reordered by Revit to cause the quickest acting filters to be evaluated first.
Example
C#
// Find all door instances in the project by finding all elements that both belong to the door
// category and are family instances.
ElementClassFilter familyInstanceFilter = new ElementClassFilter(typeof(FamilyInstance));
// Create a category filter for Doors
ElementCategoryFilter doorsCategoryfilter = new ElementCategoryFilter(BuiltInCategory.OST_Doors);
// Create a logic And filter for all Door FamilyInstances
LogicalAndFilter doorInstancesFilter = new LogicalAndFilter(familyInstanceFilter, doorsCategoryfilter);
// Apply the filter to the elements in the active document
FilteredElementCollector collector = new FilteredElementCollector(document);
IList<Element> doors = collector.WherePasses(doorInstancesFilter).ToElements();
