The unique doc field is defined in schema.xml. For example in
example/solr/conf/schema.xml we have:
<!-- Field to use to determine and enforce document uniqueness.
Unless this field is marked with required="false", it will be a required
field
-->
<uniqueKey>id</uniqueKey>
And we also have:
<field name="id" type="string" indexed="true" stored="true" required="true" />
Note it's of type "string".
