I just put up the new LIRE demo at http://demo-itec.uni-klu.ac.at/liredemo/. It’s based on the LIRE Solr plugin, which now supports arbitrary LIRE features and has been updated to fit the current Solr version 4.10.2.
Check out the new search options for searching for tags in combination with image similarity. Basically you can use the first parameter box to search for any string (ie. tags:dog) and the use the sort option below the images to re-rank the images according to the similarity of the selected picture.
Btw. thanks go to my department, the Department of Information Technology at the Faculty of Technical Sciences of the Alpen-Adria-Universität Klagenfurt for running the demo on their servers.
