Yes, Lucene can do more than I think it can, why not.
Maybe this is being done already...with Lucene... ;)
...and that is why I would like to see the object model (UML+notes).
In
the model we can find the answer if Lucene can do more than we think
:).


I believe there are tools out there that will analyze Java sources and
create UML class diagrams from that.  I believe TogetherJ or one of
those 'all in one' tools can do that.
I can do it for you, if you want - it takes ~10 minutes.

 If I understand you correctly, then maybe you are not aware of
 RemoteSearchable in Lucene.

That class cannot be used in Merger. RemoteSearchable is a class that
allows you to pass a query to another node, nothing less and nothing more
AFAIK.

 This is the point that's more clear to me now.  There is confusion
 about what Lucene is and what it is not.  Lucene does not even try to
 be what those services you mentioned are.  Their goals are different,
 they are a different set of tools.  Lucene's focus is on indexing text
 and searching it.  It is not a tool to query other existing search

I do not think so. It is all about the object model you use. If you are
not able to solve the simplest case, how can you distribute the engine
across the network? I do not mean the simple RMI gateways which marshall
parameters and send them through a network pipe, I mean the true system
that could beat google (and it is another topic...).

Moreover, I think that Lucene can do much more than you think Otis :). 
Egothor can do that, so why not Lucene?

 AFAIK.

What is Merger?  Verb, noun, an IR concept, a name of the product or
project?  Merging of results from multiple searchers from multiple
indices?

That is the difference between a simple library and a targeted
application.
