Changing Lucene analyzer or adding filter for Jena-text - to support stemming

Hi,

We've got jena-text working to do Lucene indexing, and we'd like to make it use stemming. In Lucene, I think you'd typically do this by using a SnowballAnalyzer, or creating a custom filter that uses a SnowballFilter or a PorterStemFilter.

Is there any way to configure jena-text so it will use a different Lucene analyzer? 

Thanks for any help,

Inigo

Not currently.

The assembler for the text index in

    org.apache.jena.query.text.assembler.TextIndexLuceneAssembler

passing info to

    org.apache.jena.query.text.TextIndexLucene

if you or someone wants to submit a patch.

BTW What happens if the analyser at query time is different to that at 
index construction time?
