I am not worry about fixing just one issue. Being XML aware means that 
you can do a:

(after using forms to create this Xpath query)

So you would search for "xsl" within a collection of FAQ XML documents 
that have a faq part called 'general'

I am not sure how dificult is to get there with lucene, but exist seems 
to get it already.

I do not think that users should deal with that, for them that language 
is hidden.

Semantics searching ( I thought about something similar before I knew 
the name) is about using tags to limited the search and get better results.

lucene wihtin forrest and having exist support are compatible tasks, you
