If you have an English dictionary available containing words with their lemmas, you may use my patch:
https://issues.apache.org/jira/browse/LUCENE-6254
This lemmatizer works with Danish, German and Norwegian dictionaries which are available for free. I'm not sure there exists a free English dictionary which is compatible, but please inform me in case there is one. There are probably useful English dictionaries for purchase.

Hi, IS there a way to achieve lemmatization in Solr? Stemming option is not meeting the requirement.
