Yes, having no textual documents would be a problem. (I never thought
to ask what kinds of documents you were working with :-) ) The extract_historical_years
stuff goes through the text and pulls out things that look like dates,
eg 1999, 16th century etc.
However, the range searching works on Coverage metadata, so if you
add that to your images then it should work. I think Coverage should contain
just year info, like 1999, 2000 etc, one year per metadata item, and you
can have many Coverage metadata elements per document/image.

I had already tried a variation with "-extract_historical_years" as
option with the HTMLPlug, with no change in results. However,
crux of the problem here is that I am not working with documents, but
images. For each image (jpgs) I have metadata information that
date field, but there are no documents per se. The date index
datelist classifier are both working from the date field in the metadata
files. Is it possible to get the date range search to work from
field in the metadata files, rather than a date field coming from documents?
Or, can I generate documents from the metadata?
