Thanks.
So the issue here is I already have a <uniqueKey>doctorId<uniquekey>
defined in my schema.xml.
If along with that I also want the <id></id> field to be automatically
generated for each document do I have to declare it as a <uniquekey> as
well , because I just tried the following setting without the uniqueKey for
id and its only generating blank ids for me.
*schema.xml*
<field name="id" type="string" indexed="true" stored="true"
required="true" multiValued="false" />
*solrconfig.xml*
<updateRequestProcessorChain name="uuid">
<processor class="solr.UUIDUpdateProcessorFactory">
<str name="fieldName">id</str>
</processor>
<processor class="solr.RunUpdateProcessorFactory" />
</updateRequestProcessorChain>
