I wanted to ask the properly way to query or get the length of a field in
solr.
I'm trying to ask and append fieldNorm in a result field by querying
localhost:8983/solr/uda/tvrh?q=usage:stuff&fl={!func}norm(usage)&debugQuery=on&debugQuery=on
Nevertheless, the response to this query is:

What we want is to append it to a field since we are using this field on
spark (using solr-spark) and then make some processing.
Another way we came with, is to compute fieldLength in a processor and write
it on a field, but, since norm is list on query functions we are trying to
obtain it this way.
We really appreciate your help and thanks in advice.
