Christos Constantinou commented on SOLR-2408:
---------------------------------------------
The exception occurred because the field was initially defined as int and then
changed to text. The data that were previously stored in Solr were processed as
text whereas they were stored as int - thus unhandled.

> To reproduce the exception, the following ingredients are required:
> - A query that is sorted by a date field in DESC order, ASC will not crash
> - A multivalued field like so <field name="deleted_in" type="text"
> indexed="true" stored="true" multiValued="true" />
> - Exclude the multivalued field from either the query (AND NOT
> deleted_in:XXX) or with a filter query (-deleted_in:XXX)
> - The value XXX of deleted_in MUST MATCH at least one value, if not, the
> crash will not occur.
