[jira] [Commented] (LUCENE-10392) Handle soft deletes via LiveDocsFormat

    [ https://issues.apache.org/jira/browse/LUCENE-10392?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17486213#comment-17486213 ]

--------------------------------------

+1. That'd be great. We can avoid writing docValues in refresh with soft deletes.

> We have been using doc values to handle soft deletes until now, but this is a bit of a hack as it:
>  - forces users to reserve a field name for doc values
>  - generally doesn't read directly from doc values, instead docs values help populate bitsets and then reads are performed via these bitsets
> It would also be more natural to have both hard and soft deletes handled by the same file format?
