[jira] [Created] (LUCENE-5081) Compress doc ID sets

JIRA jira@apache.org
Adrien Grand created LUCENE-5081:

             Summary: Compress doc ID sets
                 Key: LUCENE-5081
                 URL: https://issues.apache.org/jira/browse/LUCENE-5081
             Project: Lucene - Core
          Issue Type: Improvement
            Reporter: Adrien Grand
            Assignee: Adrien Grand
            Priority: Minor

Our filters use bit sets a lot to store document IDs. However, it is likely that most of them are sparse hence easily compressible. Having efficient compressed sets would allow for caching more data.
