#16450 PR: Fix DocValuesRangeIterator doc ID run ends
2.7 hours ago  4 comments  0 votes  0 watches  github-actions[bot], parkertimmins
DocValuesRangeIterator uses SkipBlockRangeIterator as a two-phase approximation. Docs in MAYBE and YES_IF_PRESENT blocks belong to the approximation, but are not necessarily query ... Consumers could then treat unconfirmed docs as matches.
    parkertimmins 3.5 hours ago:  We can safely return runs to the end of MAYBE and YES_IF_PRESENT blocks, since this iterator is a ...
    parkertimmins 3.5 hours ago:  We could alternatively just return blockIterator.docID(). This would be safe, but would mean there is little value in using docIDRunEnd(). Though I'm not sure returning docID+1 is that useful for most callers anyway.

Description Closes 14758 Add a new de-duplicating vector format that only stores unique ... De-duplication is done for vectors across all docs and fields indexed by the format. Disclaimer: This was mostly written by an AI, with me refining the implementation through prompts - ...
    kaivalnp 4.3 hours ago:  > semi-realistic case where say each vector is duplicated 20X ish times? Added now!
    kaivalnp 4.3 hours ago:  > sometimes, it deletes every doc that had a vector (yet some non-vector docs are merged) Added ...

Resolves: 16429 # Description Currently, FunctionScoreQuery hardcodes getMaxScore(int upTo) ... Lucene is forced to evaluate DoubleValuesSource and script bytecode on **every single matching ... Additionally, Lucene's default DocValuesSkipper block interval is 4,096 documents (DEFAULT_SKIP_INDE ...
    uschindler 6.3 hours ago:  Can you add a test with a constant lambda function using INCREASING as well as DECREASING as well ... This would also make clear that the above text is correct.
    rajat315315 15.1 hours ago:  I think this can be back-ported if possible as it gives considerable performance improvement in ... Function scripts are used in almost everywhere and this fix should provide an improvement. There's no harm if users are able to take advantage of it without any major upgrade. :+1:
