That's a bit of a tough one, but everyone in the search business is looking
at redefining the definition of a document in order to accomodate searches
against logical units within logical units. Soon, one might search each
server as if it were a single document, for example, in order to select
which servers to search further.

This is where knowledgebases come in handy, to tout our technology for a moment.
I'm not sure that I see where these issues would have a direct effect on
implementations of client-side highlighting. The information about what to
highlight would still have to come from the search engine.
