Hi, I need to implement grouping search using Lucene APIs on fields which are non-doc value fields.
The index is created using Solr-6.5.1 and spread across 12 shards. The group field's definition is as follows. <fieldType name="string" class="solr.StrField" sortMissingLast="true" stored="false" omitNorms="true"/> I tried to use Lucene group related APIs but it is failing as the fields are not indexed as docValues. Kindly provide your inputs/pointers on how I can achieve it outside the context of Solr using Lucene APIs. Thanks, Modassar
