[jira] [Commented] (LUCENE-3282) BlockJoinQuery: Allow to add a
custom child collector, and customize the parent bitset extraction
[ https://issues.apache.org/jira/browse/LUCENE-3282?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14202176#comment-14202176 ]
Mikhail Khludnev commented on LUCENE-3282:
------------------------------------------
[~kimchy] fwiw SOLR-5743 uses BJQScorer method to obtain matched children. Does it solves 'custom child collector' ?

> It would be nice to allow to add a custom child collector to the BlockJoinQuery to be called on every matching doc (so we can do things with it, like counts and such). Also, allow to extend BlockJoinQuery to have a custom code that converts the filter bitset to an OpenBitSet.
