2.2 days ago  4 comments  0 votes  0 watches  benwtrent, epotyom, github-actions[bot], shubhamsrkdev

#15479 PR: Add a public NumericDocValuesRangeQuery class
2.3 days ago  1 comments  0 votes  0 watches  HoustonPutman, github-actions[bot], romseygeek
SortedNumericDocValuesRangeQuery and IndexSortSortedNumericDocValuesRangeQuery both implement ... This commit adds a common base class which exposes the field, lowerValue and upperValue of the ... This can be useful for things like queryparsers which can automatically rewrite multiple ...
    HoustonPutman 2.3 days ago:  The equals method could probably be moved up, but not a big deal keeping it in each sub-class.

#15477: Introduce annotation to indicate when a DocIdStream implementation can be replayed
2.3 days ago  2 comments  0 votes  0 watches  dweiss, javasoze
Description Sometimes a DocIdStream can be replayed, e.g. RangeDocIdStream, there is not iterator state kept with the instance. Proposal: Introduce an annotation `java @Retention(RetentionPolicy.RUNTIME) public @interface ...
    javasoze 2.3 days ago:  Yup, empty marker interface does exactly the samething, annotation is just prettier and allows for ... But in this context, no difference. DocIdStreams are like iterators, it can be only scanned through once.
    dweiss 2.3 days ago:  Wouldn't an empty marker interface be easier to work with? Anyway, such changes should probably be motivated by something else, otherwise they lack the ...

2.3 days ago  5 comments  0 votes  0 watches  Pulkitg64, github-actions[bot], msokolov
Description Fixes https://github.com/apache/lucene/issues/15467. This PR implements a brute-force check to prevent duplicate reverse links during HNSW graph ... Before creating a reverse link, we iterate through all neighbors of the neighbor node to verify if ...
    Pulkitg64 2.3 days ago:  Yes, definitely. Let me do this and raise new revision.
    msokolov 2.3 days ago:  Is it possible to make this conditional on whether we're being called by the link repair process? We could add a parameter controlling whether the check is done

#15470 PR: Add only forward links when repairing HNSW merge (fixes #15467)
2.4 days ago  9 comments  0 votes  0 watches  Pulkitg64, github-actions[bot], msokolov
This is what I was thinking -- when "repairing" only add links *from* the node being repaired and ... This is needed because ordinarily we are adding nodes in order and each node is only added once, so ... So we would have to check for duplicates when making links, or we can just forgo adding the reverse ...
