I added a line about lucene:
• Powered by Lucene 9.0, bringing in new analyzers and better space
efficiency of postings
Please have a look at Lucene 9 changes
<https://lucene.apache.org/core/9_0_0/changes/Changes.html> to see if any other
are worth a mention. I think we should have more than one bullet from lucene-9.
The ones I have found that directly affect Solr are:
* Removal of SimpleFSDirectoryFactory which was done in:
LUCENE-9264: SimpleFSDirectory has been removed in favor of NIOFSDirectory.
(Yannick Welsch)
I believe this was committed in master branch before the split, and did not
get a SOLR changes entry
* New snowball stemmers: Hindi, Indonesian, Nepali, Serbian, Tamil and Yiddish.
New stoplist: Indonesian (LUCENE-9220, LUCENE-9605)
* Add NorwegianNormalizationFilter (LUCENE-9929)
PS: We should probably also consider adding new schema <fieldType
name="text_XX"> for the new languages? That can wait until 9.1 though...
