Id field as long type

I'm trying to use Id field as Long and getting this error:

ERROR: Error CREATEing SolrCore 'brands': Unable to create core 
[brands] Caused by: uniqueKey field (id) can not be configured to use a 
Points based FieldType: plong

Here is my schema.xml:

<?xml version="1.0" encoding="UTF-8"?>
<schema name="brands-config" version="1.6">
<uniqueKey>id</uniqueKey>
<fieldType name="plong" class="solr.LongPointField" docValues="true"/>
<fieldType name="string" class="solr.StrField" sortMissingLast="true" docValues="true"/>
<field name="name" type="string"/>
<field name="id" type="plong" multiValued="false" indexed="true" required="true" stored="true"/>
</schema>

My solrconfig.xml is basic one - only removed the part mentioned in this thread but it didn't help.

Is there any way to make my id field type long? I need it this way to avoid too much mapping.

As described here you can't use a point based field as uniqueKey. Instead, you could use the string type.

I'm really not sure why you need to have long datatype. To answer your question Solr query elevation component uses the String as a key and hence your unique key cannot be a long.

If you need to work around on this then you might consider creating a copy field and have that as a long and use if for your operations.
