I think this assumes that all data that would ever be queried by CQL is 
well structured and semantically meaningful.  And I think that's a very 
bad assumption.

Take, for example, an HTML (or, for the sake of sanity, XHTML) page.  
Proximity within the text of an anchor tag or a div or a table cell /may 
very well be all the context you have/.

What if your indexed field contains an XML document?  Again, it seems 
that same element could be a metric.
