> This ticket introduces the ReRankingQParserPlugin which adds query Reranking/Rescoring for Solr. It leverages the new RankQuery framework to plug-in the new Lucene QueryRescorer.
> See ticket LUCENE-5489 for details on the use case.
> Sample syntax:
> {code}
> q={!rerank mainQuery=$qq reRankQuery=$rqq reRankDocs=200}
> {code}
> In the example above the mainQuery is executed and 200 docs are collected and re-ranked based on the results of the reRankQuery.
