I need to get the ID, and other info, for every file attached to a Customer record. I created a Saved Search in the UI which gives me what I need. However if I load and run the search, or create a search, in a User Event Script, in beforeLoad, (or in the Debugger) I get no values. If I use search.lookupFields I get the information from only one file. In the code below, I know that Customer ID 3 has two files attached. In the log you can see it found two entries, but I get no information. And lookupFields gives the same information twice.

search.create({
type: "customer",
filters:[{"name":"internalid","operator":"anyof","values":["3"]}],
columns:[
{"name":"url","join":"file"},
{"name":"filetype","join":"file"},
{"name":"companyname"}
]
}).run().each(function(res) {
log.debug('url: '+res.getValue('url')+', type: '+res.getValue('filetype')+', name: '+res.getValue('companyname'));
var fld = search.lookupFields({
type: search.Type.CUSTOMER, 
id: 3, 
columns: ['file.internalid','file.name','file.filetype']
});
log.debug(fld);
return true;
});

Log:
