[jira] [Created] (SOLR-8769) CloudMLTQParser does not use uniqueKey field name for exclusion

Erik Hatcher created SOLR-8769:
----------------------------------

             Summary: CloudMLTQParser does not use uniqueKey field name for exclusion
                 Key: SOLR-8769
                 URL: https://issues.apache.org/jira/browse/SOLR-8769
             Project: Solr
          Issue Type: Bug
            Reporter: Erik Hatcher


Using the {{\{!mlt}}} query parser in cloud mode on a schema with a non-"id" uniqueKey, the main "like this" document won't be excluded properly due to this code:

{code}
realMLTQuery.add(createIdQuery("id", id), BooleanClause.Occur.MUST_NOT);
{code}

See also https://github.com/apache/lucene-solr/blob/813ca77250db29116812bc949e2a466a70f969a3/solr/core/src/java/org/apache/solr/search/mlt/CloudMLTQParser.java#L166

Like SimpleMLTQParser, it needs to use the uniqueKey field with this type of code: {{req.getSchema().getUniqueKeyField().getName()}}
