Hi Erik,
While you might be right in this example (using Field.Keyword), I can
see how this would still be a problem in other cases. For instance, if I
were adding more than one word at a time in the example I attached.

Changing these to Field.Keyword gets it to work. I'm delving a little
bit to understand why, but it seems if you are adding words
individually anyway you'd want them to be untokenized, right?
