You might want to look at goxml.com (http://www.goxml.com) for one approach 
to this problem. The engine searches for the search term(s) in XML 
documents that it knows about and returns you basically just a standard 
search-engine sort of listing of hits. However, down the left side of the 
page of hits is a listing of the XML element types in which it found any 
hits; you narrow the result set by selecting one of these element types, 
which provides a "context" of sorts when search terms might appear in more 
than one XML application. (Try "detour" as the search term to get a sense 
of how this works.)

IMO, this neatly sidesteps the problem of having to construct vertical 
search engines like you describe, leaving the selection of context up to 
the user.
