We need to:
* **deploy the search/extra-analysis-slovak plugin with the Slovak stemmer** ← we are here
* deploy the analysis config that expects the stemmer to be there
* re-index Slovak Wikis with the new analysis chain enabled
We refactored the search/extra project so that search/extra-analysis-slovak is a sub-module that generates a separate plugin. We need to re-deploy the new search/extra //without// the Slovak stemmer, and the new search/extra-analysis-slovak //with// the Slovak stemmer.
The plugins need to be updated and the clusters restarted.
