Perhaps because they have been investing a lot in a newproduct named KMS (Knowledge
Management Suite) and
kind of forgetting BRS itself.

Perhaps you should read again what I said. The product is not BRS/Search,it is
Dataware II Publisher (formely EPMS). It is a "version"  of BRS
because it uses pretty much the same basic technology. On the other
hand, it is entirely different because the internal format is SGML,
so it allows for searchs in the SGML style (as opposed to "paragraph"
qualification). As the manual says (page 136): "You can search your
publication by SGML element tags. For example, you
can search your publications by the TITLE element".

You can also design style sheets based on the SGML tags for printing
and displaying purposes. BRS itself does not know anything about
SGML, but Dataware II Publisher certainly does. I have been using
the product for several months now. I have a number of publications
in it, including some of the Shakespeare works (markup by Jon Bosak - Moby Lexical
Tools)

I am not as knowledgeable as you on SGML/XML so I can not garantee
100% compatibility with SGML. What I can say is that I like what
I have. To me it looks like what any XML user would like to
see in a search engine.
