But most people want the best possible combination of both, something like:
(raw_field:word OR stemmed_field:word^0.5)
and it is nice that Solr allows such arrangements but it would be even
nicer to have some sort of automatic "take this field, transform the
contents in a couple of ways and do some boosting in the order given".
At least this would be my wish for the recent question about the one
feature I would like to see.
Or even better, allow not only a hierarchy of transformations but also a
hierarchy of fields (like in dismax, but with the full power of the
standard request handler)
