I've built systems with proximity across elements. Imagine this case:
<author>C. J. Cherryh</author>
<title>Brother at Arms</title>
I'm looking to see if Cherryh wrote "Brother at Arms". The search is:
Author=cherryh prox/unit=element/distance=1 title="brother at arms"
That means that the author must occur in the element immediately
preceeding the title.
