Language support and linguistics in Apache Lucene™ and Apache Solr™ and the eco-system by Gaute Lambertsen and Christian Moen.
Slides from Lucene Revolution May, 2013.
Good overview of language support and linguistics in both Lucene and Solr.
A few less language examples at the beginning would shorten the slide deck from its current one hundred and fifty-one (151) count without impairing its message.
Still, if you are unfamiliar with language support in Lucene and Solr, the extra examples don’t hurt anything.
