      Description

      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:

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

      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()
