[jira] [Commented] (LUCENE-10015) Remove VectorValues.SimilarityFunction, remove NONE

    [ https://issues.apache.org/jira/browse/LUCENE-10015?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17384330#comment-17384330 ] 

Adrien Grand commented on LUCENE-10015:
---------------------------------------

In this case, nextDoc would hopefully return the single matching doc without linearly checking every doc. When I mentioned skip lists, I was thinking of how {{advance(int target)}} allows skipping over many documents efficiently.

> This stuff is HNSW-implementation specific. It can be moved to a codec parameter.
> The NONE option should be removed: it just makes the codec more complex.
