Using pint field as uniqueKey

[Michael Kondratiev]

I'm trying to set up uniqueKey ( what is integer)  like that:


        <field name="id" type=“pint" indexed="true" stored="true" 
required="true" multiValued="false"/>
        <uniqueKey>id</uniqueKey>


But when I upload configuration into solr i see following error:

    

    uniqueKey field (id) can not be configured to use a Points based FieldType: 
pint

If i set type=“string” everything seems to be ok.
