Hello all,
I'm experimenting with the "Distributed Search" bits in the nightly
builds and I'm facing a problem.
I have on my schema.xml some dynamic fields defined like this:
<dynamicField name="$*" type="double" indexed="true" stored="true" />
<dynamicField name="@*" type="string" indexed="true" stored="true"
multiValued="true" />
<dynamicField name="*" type="string" indexed="true" stored="true" />
When hitting a single shard the following query works fine:
http://<solr>/select?q=*:*&fl=ts,$distinct_boxes
But when I add the "&distrib=true" parameter I get a NullPointerException:
java.lang.NullPointerException

The "$" in "$distinct_boxes" appears to be the culprit somehow, the query:
<http://<solr>/select?q=*:*&fl=ts,distinct_boxes&distrib=true>
works without errors, but of course doesn't retrieve the field I want.
Funnily enough when requesting the uniqueKey field there are no errors:
<http://<solr>/select?q=*:*&fl=tid,ts,$distinct_boxes&distrib=true>
But somehow the data from the field "$distinct_boxes" doesn't appear in
the output.
Is there some workaround? Using "fl=*" returns all the data from the
fields that start with "$" but it severely increases the size of the
response.
