This whole issue was discussed previously in a bit more detail. See the
thread entitled "Endings databases of two languages":
Unless you work out a way of merging endings databases of two or more
languages, as Geoff and I had previously discussed, you won't get the
endings fuzzy matching to work in multiple languages simultaneously.
Of course, this doesn't prevent you from indexing documents in multiple
languages, as long as they use the same character encoding, ISO-8859-1
in this case. You can even put together combined bad_words lists and
synonyms dictionaries, but if you want the endings algorithm to work in a
multi-lingual setting, you either need to figure out how to combine the
databases, or let the user select the language preference via different
According to Geoff Hutchison:
