Today I gave a talk on LIRE at the ACM Multimedia conference in the open source software competition, currently taking place in Barcelona. It gave me the opportunity to present a local installation of the LIRE Solr plugin and the possibilities thereof. Find the slides of the talk at slideshare: LIRE presentation at the ACM Multimedia Open Source Software Competition 2013
The Solr plugin itself is fully functional for Solr 4.4 and the source is available at https://bitbucket.org/dermotte/liresolr. There is a markdown document README.md explaining what can be done with plugin and how to actually install it. Basically it can do content based search, content based re-ranking of text searches and brings along a custom field implementation & sub linear search based on hashing.
