title: Snowball stemmers have been upgraded | ||
area: Analysis | ||
details: >- | ||
Lucene 10 ships with an upgrade of its Snowball stemmers. | ||
For details see https://github.com/apache/lucene/issues/13209. Users using | ||
Snowball stemmers that are experiencing changes in search behaviour on | ||
existing data are advised to reindex. | ||
impact: >- | ||
The upgrade should generally provide improved stemming results. Small changes | ||
in token analysis can lead to mismatches with previously index data, so | ||
existing indices using Snowball stemmers as part of their analysis chain | ||
should be reindexed. | ||
