Subject [jira] [Comment Edited] (LUCENE-6959) Remove ToParentBlockJoinCollector
Date Thu, 26 Jan 2017 12:26:24 GMT

bq. Do we really need the {{origChildQuery}} anymore?

In case the query gets rewritten and if the query happens to get cached?

> This collector uses the getWeight() and getChildren() methods from the passed in Scorer,
which are not always available (eg. disjunctions expose fake scorers) hence the need for a
dedicated IndexSearcher (ToParentBlockJoinIndexSearcher). Given that this is the only collector
in this case, I would like to remove it.
