> 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=*:*&rq={!rerank reRankQuery=$rqq reRankDocs=200 reRankWeight=3}
> {code}
> In the example above the mainQuery is executed and 200 docs are collected and
> re-ranked based on the results of the reRankQuery.
