Thanks for the info bugmenot, very helpful.
Firstly, this is just a play toy more than anything, I liked the SV software and I love Flickr so combining the two was a natural way to make me smile :)
Second, not sure about SimpleViewer, but TiltViewer allows a choice of "ANY" tags or "ALL" tags, so the Clinton search described should work, providing the images have been tagged with both "hillary" and "clinton"... but point taken, it is a long way from perfect!
You're right that I could allow quotes in the search string and process the query to allow for a better search and I will look to do that the next time I have a spare 5 mins!
Regarding negative quotes, it would be good if Simple and Tiltviewer allowed you to process more of the Flickr API commands. This page - http://www.simpleviewer.net/tiltviewer/ … tions.html - says for more Flickr commands, follow a link to the Flickr API command list - so perhaps I can?
