Michael McCandless commented on LUCENE-9674:
--------------------------------------------
I don't see any change in {{luceneutil}} nightly {{VectorSearch}} QPS:
[https://home.apache.org/~mikemccand/lucenebench/VectorSearch.html]
But maybe that is expected – [~sokolov] is this benchmark task doing any
advance? Or is it straight KNN search?
> Faster advance on Vector Values

> Key: LUCENE-9674
> URL: https://issues.apache.org/jira/browse/LUCENE-9674
> Project: Lucene - Core
> Issue Type: Improvement
> Components: core/codecs
> Affects Versions: master (9.0)
> Environment:
> Reporter: Anand Kotriwal
> Priority: Major
> Time Spent: 4h
> Remaining Estimate: 0h
>
> The advance() function in the class Lucene90VectorReader does a linear search
> for the target document.
> To make it faster we can do a binary search over the "ordToDoc" array which
> will make the advance operation take logarithmic time to search.This will
> make retrieving vectors for a sparse set of documents efficient.
