Atri Sharma commented on LUCENE-8877:
-------------------------------------
Any thoughts on this? I am envisioning eventually getting to a state where the
underlying data structure used is opaque to IndexSearcher API. This should
allow an abstraction with high degree of flexibility
> TopDocsCollector Should Not Depend on Priority Queue

> Key: LUCENE-8877
> URL: https://issues.apache.org/jira/browse/LUCENE-8877
> Project: Lucene - Core
> Issue Type: Improvement
> Reporter: Atri Sharma
> Priority: Major
>
> TopDocsCollector is tightly coupled to the notion of priority queue, which is
> not necessarily a good abstraction to have since the collector really just
> needs an interface to iterate on and hold docID and score, with possibly
> shard indexes.
>
> We should rewrite this to a more simplistic interface with priority queue
> being the default implementation
