Description

When I go to sort on a multi-valued field in a 2 shard collection, which has trie fields the query fails.

To reproduce we need 2+ shards, a multi-valued trie field and "desc" sort criteria.

Here's my schema

<dynamicField name="*_is" type="int" indexed="true" stored="true" multiValued="true" docValues="true"/>
<fieldType class="solr.TrieIntField" docValues="true" name="int" positionIncrementGap="0" precisionStep="0"/>

<dynamicField name="*_i" type="pint" indexed="true" stored="true" multiValued="true"/>
<fieldType name="pint" class="solr.IntPointField" docValues="true"/>

Now If I add a few docs

[
{"id" : "1", "test_is" : ["1", "2", "3", "4", "5"], "test_i" : ["1", "2", "3", "4", "5"]},
{"id" : "2", "test_is" : ["1", "2", "3", "4", "5"], "test_i" : ["1", "2", "3", "4", "5"]},
{"id" : "3", "test_is" : ["1", "2", "3", "4", "5"], "test_i" : ["1", "2", "3", "4", "5"]}
]

Works:

http://localhost:8983/solr/gettingstarted/select?q=*:*&sort=field(test_i,max)%20desc

 

Doesn't Work:

http://localhost:8983/solr/gettingstarted/select?q=*:*&sort=field(test_is,max)%20desc

 

To be more clear when I say it doesn't work , the query throws and error and here's the stack trace for it:
