Replacement of CollapsingTopDocsCollector

In Lucene 7.x, CollapsingTopDocsCollector is removed, is there any replacement of it?

Hi,

I'm wondering if you mean Elasticsearch's
org.apache.lucene.search.grouping.CollapsingTopDocsCollector.
Elasticsearch 6.4.0, the latest version, is shipped with this class.
https://github.com/elastic/elasticsearch/tree/v6.4.0/server/src/main/java/org/apache/lucene/search/grouping

I'm not sure if Lucene had been having such Collector class so far.

Regards,
Tomoko
