Ah... I see now that you are using the keyword tokenizer that should
preserve the phrase structure of the text.
You haven't detailed the exception stack trace.
What are the numbers in terms of number of values and average length of each
value?

Are you sure you want to facet on a text field??? That will facet on the
individual terms, which isn't usually very useful.
Usually, people want to facet on full phrases or entire strings, so they do
a schema copyField from the text field to a string field and then facet on
the string field.

Subject: NPE when faceting TEXTfield in a distributed search query
Hi,
I have a nullable TextField with field type as follows(field
name=fun_group):-
<fieldType name="lowercase_sort_missing_first" class="solr.TextField"
sortMissingFirst="true" positionIncrementGap="100">
<analyzer><tokenizer class="solr.KeywordTokenizerFactory"/>
<filter class="solr.LowerCaseFilterFactory"/></analyzer>
</fieldType>
field definition is:-
<field name="fun_group" type="lowercase_sort_missing_first" indexed="true"
stored="true" multiValued="false"/>
I am running a distributed search(using shards= param) across 13 shards
while faceting on fun_group with the following params:-
http://<shard1>/solr/mycore/select?facet=true&facet.field=fun_group&facet.mincount=1&rows=0&facet.limit=10000&facet.offset=0&q=(((my_id:4024
AND ((flag:1 OR flag:0)))) AND
class_id:2604)&shards=<shard1>/solr/mycore,<shard2>/solr/mycore,<shard3>/solr/mycore,<shard4>/solr/mycore,<shard5>/solr/mycore,<shard6>/solr/mycore,<shard7>/solr/mycore,<shard8>/solr/mycore,<shard9>/solr/mycore,<shard10>/solr/mycore,<shard11>/solr/mycore,<shard12>/solr/mycore,<shard13>/solr/mycore
I get Internal Server Error on shard6. In the logs, I see the NPE from
org.apache.solr.servlet.SolrDispatchFilter.
If I change the facet.limit from 10000 to 5000 keeping the
facet.offset=0,there are no exceptions. Now again if try facet.limit=5000
and facet.offset=5000 , I get the same exception. I tried facet.limit=4000
and facet.offset=5000, it worked fine. Please help
