Top syntax to display null fields when using 'by'?

When I use 'top' to create a top n list of fields, and I add two fields, using by, so:

top field1 by field2

if either field is not present in a result, it does not display in the list. I want to display events in my results even the secondary field is null. Is there any way to do this?

For example:

top infected person by infection

Even if I don't know what infection it is, I still want them to show up on the list of infected people, and I still want to see the infection if it is available.

The best way to do this is to use the fillnull command to make the desired fields dense. In this case, you could try:

... | fillnull value=NULL person infection | top person by infection
