SWISH-E folks--

I'm trying to index XML files (Dublin Core pulled out of an OAI 
harvester, to be precise), and would like to be able to search for a 
unique identifier based on the Path header, which in turn is based on 
the OAI identifier.  My config file includes:

  ExtractPath docnum regex ![-:/\]!_!g

I can display the docnum--for example 
"oai-etd-ohiolink-edu-case1055429377"--but if I try searching for it, I 
get no results:

=========
$ swish-e -f xtest -w docnum="oai-etd-ohiolink-edu-osu1059673277"
# SWISH format: 2.4.2
# Search words: docnum=oai-etd-ohiolink-edu-osu1059673277
# Removed stopwords:
err: no results
=========


Am I overlooking something to make the docnum searchable?  My conf file 
is below.
