I'm using dates in my metadata.xml file, and although searching and browsing
seem to work correctly, the display of the date info is strange.

I can't find anything specifying the format in any of the greenstone pdf
files, so I went with what I found online for the Dublin Core: YYYY-MM-DD.

However, the display of a field such as this:
<Metadata name="Date" mode="accumulate">1878-01-03</Metadata>

will be shown as:
Date: 1- _textmonth-0_ 1878

This display shows up both in the datelist classifier and in the
documentText format.

2) Searching Question:
Is there a way to allow the user to search (not browse) within range of
dates, using either the MG or MGPP search engines?
