  <!> Gotchas:
   * Although the Lovins stemmer is described as faster than Porter/Porter2, 
practically it is much slower in Solr, as it is implemented using reflection.
   * Neither the Lovins nor the Finnish stemmer produce correct output (as of 
Solr 1.4), due to a 
[[http://article.gmane.org/gmane.comp.search.snowball/1139|known bug in 
Snowball]]
+  * The Non-English stemmers are sensitive to diacritics. Think carefully 
before removing these with something like `ASCIIFoldingFilterFactory` before 
stemming, as this could cause unwanted results.
