The eForum search facility is a plugin factory, because we wanted to separate
the forum from the search engine component. The default plugin is based on
Lucene. Anyone can write a plugin that works with another Search Engine.
The purpose of the plugin is to index eForum messages.

If you need to plug-in a generic search in Expresso Framework, you need
to ask what are going to index. People can index any Java object they
want. So how can you provide a generic interface?  Are you trying
to define a sort of higher level JAXP (Java for XML API ) that consolidates
a standard interface to SAX parser and TRaX? I think this is harder,
because you need to look at as many as Java Search Engine API as you
can find on the Net and then try to abstract an interface for them?
