--------------------------------------

Meanwhile I 've asked if Lucene has some sort of "AutomaticAnalyzerResolver based on Locale":

> we find this code:
>     private IndexWriter constructIndexWriter() throws IOException {
>         return new IndexWriter(indexDirectory, new StandardAnalyzer());
>     }
> which says that lucene uses StandardAnalyzer, however when we insert words like "werken", "gewerkt" and search for "werkte", it doesn't find it.
> The solution is to use a DutchAnalyzer instead.
> A solution might be: ask the language code of the daisy branch,
> then check if there's a Analyzer for that (for example "nl" => DutchAnalyzer)
> and do a fall back on StandardAnalyzer if it doesn't exist.
> Problem is that the current FullTextIndexImpl probably uses a singleton analyzer, independ of in which branch scope it's processed.
