-------------------------------------
Issue Type: New Feature (was: Bug)
> Evaluate/Design a MatchMost/MatchAll doc set
> --------------------------------------------
>
> Key: SOLR-10057
> URL: https://issues.apache.org/jira/browse/SOLR-10057
> Project: Solr
> Issue Type: New Feature
> Security Level: Public(Default Security Level. Issues are Public)
> Reporter: Michael Sun
> Priority: Major
>
> Per discussion in SOLR-9764 Design a memory efficient DocSet if a query
> returns all docs, if a DocSet matches most of documents, current
> implementation using BitDocSet can be optimized. This JIRA is to evaluate and
> design an optimized DocSet for these use cases.
> The basic idea is to use an inverted integer list to enumerate all doc ids
> that doesn't match. If the DocSet matches most of docs, it can be pretty
> efficient. Meanwhile other ideas are welcome.
