[EP-underground] Questions about subjects

I've got a couple of questions regarding the use of subjects in the Eprints 
software.  The first one is fairly simple.  When a user does a keyword 
search, are the words used in the subject headings searched as well?

The second question is a little more complicated, because I'm trying to use 
Eprints to archive some specialized documents.  These documents include 
various data tables from the US Census Bureau.  Most of the documents 
include information for a unique region in the state.  A few documents 
include a single statistic about every region in the state.  I'm planning 
on setting up a hierarchy, similar to subject, called region.

A short version of this hierarchy might look like:

    County
    County : Dallas
    County : Polk
    County : Story

I have a document called "Median Household Income by County", which 
includes the median household income for all counties in the state.  I want 
to make sure that someone doing a subject search will be able to find it, 
even if they're looking for the median household income for Polk County.

What kind of subject hierarchy should I use, and how should I enter this 
document into Eprints?  Should I select every county on the region list, or 
is there a better way?

Thanks,
Alan Schmitz
