[jira] [Commented] (SOLR-9331) Can we remove ReRankQuery's length constructor argument?

Hi [~cpoerschke],

Sorry I've been slow responding to your work with the re-ranker.

Now that SOLR-9252 is complete the next step is to deploy stored models in the reranker. I'll be working on this for the Solr 6.3 release. That will be a good time for me to test out any changes you make in the reranker. 

My plan for deploying models in the reranker is to add a classify() function query that returns the score from a logistic regression classifier. The classify() function query will initially work with the logistic regression models created in SOLR-9252. 

Then the rerank query would be:

{code}
{!func}classify(...)
{code}

> Can we remove ReRankQuery's length constructor argument? It is a ReRankQParserPlugin private class.
> proposed patch summary:
> * change ReRankQuery.getTopDocsCollector to use its len argument (instead of the length member)
> * remove ReRankQuery's length member and constructor argument
> * remove ReRankQParser.parse's use of the rows and start parameters
> motivation: towards ReRankQParserPlugin and LTRQParserPlugin (SOLR-8542) sharing (more) code
