Ultraseek Server is definately production-grade. We added XML
as a supported document type in September 1998. It's a modern,
high-quality IR engine, that scales to millions of documents
and millions of queries per day. And you can buy it now.

XML documents are treated like HTML documents, Microsoft Word
documents, or PDF documents. Extract the text and meta data
(helped by a DTD-specific map), and index them. All are a
searchable with a common model, but without complex XQL-like
queries.

And try the query suggested earlier on www.go.com (same basic
internal algorithms as Ultraseek Server):

  have you got anything about the causes of hyperinflation in 
    inter-war Germany?

Turns out that the first hit is a good description of the causes
of hyperinflation in inter-war Germany:
