But the StandardAnalyzer is no more appropriate for non-English,
correct? So unless we have the non-English analyzers, then there is no
value in using the StandardAnalyzer over the simple? clucene is still
trying to become compatible with Lucene 2 (I think it's largely done,
but not released yet). If these analyzers are for Lucene 3.0, is it
possible that it would take substantial work to port them to clucene
which is still stuck in Lucene 1 compatibility?
