[jira] [Commented] (LUCENE-5084) EliasFanoDocIdSet

    [ https://issues.apache.org/jira/browse/LUCENE-5084?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13696349#comment-13696349 ] 

Adrien Grand commented on LUCENE-5084:
--------------------------------------

Thanks for opening this issue, Paul! Since Elias-Fano encoding encodes data on fixed numbers of bits, you might be interested in using PackedInts.getEncoder and PackedInts.getDecoder which return encoders/decoders able to efficiently bulk-encode/decode sequences of packed integers. They support both byte[] and long[] as an underlying storage.
