Good !
I am attaching the updated script because the initial one had a few
problems.
While this script is specific to the date/document format at hand,
modifying it to process some other date format, or field, would be quite
easy.

Recoll will only handle one field as the document date, meaning only the
"date" field can be queried using the specific date/time interval syntax.
However, it might be useful to add other dates from the document, giving
them other field names (ie: date1, date2, etc.). They will be processed as
ordinary text fields, but if they are in YMD format (as opposed to DMY),
you should be able to do something with wildcards (just specifying '1' or
'2' as the first character will dramatically reduce the processing time).
You'll need to add your fields to the "fields" configuration file to get
them to be indexed. See:

http://www.lesbonscomptes.com/recoll/usermanual/rcl.program.fields.html
http://www.lesbonscomptes.com/recoll/usermanual/rcl.install.config.html#rcl.install.config.fields
+ comments in the fields file.
I was thinking that I needed to write a tutorial, but it already exists :) :

No, just one date field for now. You could add the file mtime as one of the
custom fields above, but, as said, it will be processed as ordinary text,
not like a date.
Actually, it would not be impossible to modify recoll to handle multiple
date fields (but not trivial either). If other people think that this would
be an interesting feature, please speak up.
Cheers,
