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) -Michael
