ifference?
Why I am asking the question. In our product, we have got an incident related
to different result set for below two queries.
1. Lucene Query String : report -kind:"AAD.AnalysisApplication_Bookmark"
-kind:BIWidgets -kind:Discussions -kind:"DSL.MetaDataFile
on we
actually saw an improvement in our overall indexing time and some
performance improvements across the board.
Thanks for all the feedback.

Marc,
We also ran into this problem on updating to Lucene 9.5. We found it
sufficient in our use case to just bump up LRU cache in the constructor to
a high enough value to not pose a performance problem. The default value
of 4k was way too low for our use case with millions of unique facet
tation (or something even more
fine-tuned to your needs)?

Hello,
I've done bisect between 9.4.2 and 9.5 and found the PR affecting my
particular set up : https://github.com/apache/lucene/pull/12093
This is the switch from UTF8TaxonomyWriterCache to an
LruTaxonomyWriterCache. I don't see a way to control the size of this
cache to never expel
r.add(FacetLabel) are significantly slower for me.
https://github.com/apache/lucene/blob/releases/lucene/9.5.0/lucene/facet/src/java/org/apache/lucene/facet/FacetsConfig.java#L383
I don't know what is special about my documents that I would be seeing this
change. I'm going to start droppin
Hi Marc,
You could try git bisect lucene repository to pinpoint the commit that
caused what you're observing. It'll take some time to build but it's a
logarithmic bisection and you'd know for sure where the problem is.
