Hi
I have a problem doing facet search on a doc value field in a multi
shard collection. Any ideas what I may be doing wrong?
My Solr schema specifies fieldA as a docvalue type and I have created a
two shard collection using Solr 4.4.0.
When I do a facet search on fieldA with a "large" facet.limit then the
query fails with the below exception
A "large" facet.limit seems to be when (10 + (facet.limit * 1,5)) *
number of shards > rows matching my query
The exception does not occur when I run with a single shard collection.
It can easily be reproduced by indexing a single row and querying it, as
the default facet.limit is 100.
The facet query received by Solr looks as follows:
576793 [qtp170860084-18] INFO org.apache.solr.core.SolrCore ¦
[trym_shard2_replica1] webapp=/solr path=/select
params={facet=true&start=0&q=*:*&distrib=true&collection=trym&facet.field=fieldA&wt=javabin&version=2&rows=0}
status=500 QTime=20
One of the "internal query" send by Solr to its shard looks like
576783 [qtp170860084-19] INFO org.apache.solr.core.SolrCore ¦

My schema.xml contains the following lines (among others :-))
<dynamicField name="*A" type="dlong" indexed="false" stored="true"
docValues="true" required="true"/>
...
<fieldType name="dlong" class="solr.TrieLongField"
docValuesFormat="Disk" precisionStep="0" positionIncrementGap="0"/>
Any help is appreciated. Thanks in advance.
Best regards Trym
