Subject Re: Stemming and other tokenizers

You'll not be able to detect language and change stemmer on the same field in one go. You
need to create one fieldType in your schema per language you want to use, and then use LanguageIdentification
(SOLR-1979) to do the magic of detecting language and renaming the field. If you set langid.override=false, and populate your "language" field with the known language, you will probably
get the desired effect.
