Specifying Flickr tag wildcard

Is it possible to specify a wildcard character when searching Flickr tags? For example, suppose I want to find all geotagged pictures, I would normally have to specify several tag URLs e.g.

http://www.flickr.com/photos/tags/geotagged
http://www.flickr.com/photos/tags/geotag
http://www.flickr.com/photos/tags/geotags

etc. but with a wildcard I could in theory at least search for

http://www.flickr.com/photos/tags/geotag*

Anyone know if this is possible? Same applies to other tagging services such as Technorati and del.icio.us.
