> if you want to have a stemmed and an unstemmed version of a token one for
> recall and one for precision you have to do two fields today in most of the
> cases. Yet, most of the stemmers respect the keyword attribute so we could
> add a token filter that emits the same token twice once as keyword and once
> plain. Folks would most likely need to combine this
> RemoveDuplicatesTokenFilter but that way we can have stemmed and unstemmed
> version in the same field.
