Bulgarian stemmer should stem the same way these words, but it does not. биография =\> "биограф" биографията =\> "биографи" The correct is "биограф". The problem is huge because it happens in very common case of stemming. I wrote the document used to implement the algorithm and there the logic looks correct. I guess there is some mistake in implementation. Thanks a lot ---

Elasticsearch uses analyzers from Lucene. Here is the source code of this specific [bulgarian stemmer](https://github.com/apache/lucene-solr/blob/master/lucene/analysis/common/src/java/org/apache/lucene/analysis/bg/BulgarianStemmer.java). Feel free to file an [issue in Lucene](https://issues.apache.org/jira/projects/LUCENE/issues/LUCENE-9334?filter=allopenissues) or create your own patch. ---
