[jira] [Commented] (LUCENE-10016) VectorReader.search needs
rethought, o.a.l.search integration?
[ https://issues.apache.org/jira/browse/LUCENE-10016?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17372056#comment-17372056 ]
Michael Sokolov commented on LUCENE-10016:
------------------------------------------
Hmm I think we expect that any approximate nearest-neighbor algorithm is going to have a parameter that trades off speed for accuracy. Fanout is not a good name for it, but I think it is a useful knob

> Key: LUCENE-10016
> URL: https://issues.apache.org/jira/browse/LUCENE-10016
> Project: Lucene - Core
> Issue Type: Task
> Reporter: Robert Muir
> Priority: Blocker
> Fix For: 9.0

>
> There's no search integration (e.g. queries) for the current vector values, no documentation/examples that I can find.
> Instead the codec has this method:
> {code}
> TopDocs search(String field, float[] target, int k, int fanout)
> {code}
> First, the "fanout" parameter needs to go, this is specific to HNSW impl, get it out of here.
> Second, How am I supposed to skip over deleted documents? How can I use filters? How should i search across multiple segments?
