Here's a possible wish list item that I don't yet see on the list of  
future enhancements:  Collation (ordering) of meta tags so one could  
limit a search by

metaname < quantity

in addition to string comparison (metaname = word)

For example, dates stored as metatags (yyyymmdd):

swish-e -w "date < 17760704"

Another is a collection I have where individual documents have access  
attributes (say ordered 0,1,2,...), where higher means more access.   
I  spider into a common index, with each @url entry starting at a  
page that lists all documents (to which  swishe has access),  
recording the access level in the access metatag.  Although access to  
the document itself is separately restricted by an application, I  
want to avoid information leakage in the description property, so:

swish-e -w "access = (0 or 1 or 2)"  for someone with access level 2

But with a collation order, I could also use swish-e -w "access <  
$user_access_level"

Admittedly this is much less compelling than date sequences.
