[WebHelp] Language support for search

Dear All,

looking into the language support I can see only en/es/jp stopwords and
de/en/fr stemmers:

http://snapshots.docbook.org/xsl/webhelp/template/search/

Has anybody implemented additional ones?

In foreseeable future I'd like to cover also pt/it/cs/nl. I have some ideas,
based on lucene analyzers, but why not use something existing ;-)

Thanks,

Jan
