You wouldn't be able to query just the AutoManufacturer record though.

You'd need to perform a join across tables, e.g.:-

when
  $p: Part( partVendor == "PV999999" )
  $m: Model( partsList contains $p )
  $b: Brand( brandModels contains $m )
  $a : AutoManufacturer( brandsCollection contains $b )
then
  System.out.println( $p + ", " + $m + ", " + $b + ", " + $a );
end

Excuse my ignorance I am relatively new to Drools, can you please expand on
the following:

"...(...$p.getPartsName()...) "

This is where I am having a hard time on how to navigate into the nested
collections. Or are you saying to insert the PART, MODEL, BRAND, etc as
individual facts?  How would I relate it back Automanufacturer fact?
