I have noticed that, an issue(https://issues.apache.org/jira/browse/LUCENE-2725) was created to add Bengali Analyzer into LUCENE but it was nearly 7(seven) years ago. I didn't see any update in that issue on JIRA.
In few days ago, I am in need of analyzing my Bangla documents(I have used Elasticsearch). I have contacted with a member of elastic.co. He suggested me to do a contribution with my research codes to LUCENE.
I have started reviewing the codes of "modules/analysis". I have noticed that, Hindi analyzer is added already. By following HindiAnalyzer and HindiStemmer codes, I have developed BengaliAnalyzer for LUCENE.
I have followed two research papers and implemented features which are needed.
Please give me instructions, what should I do next.
