Hi Iam trying to integrate a image retrieval system (Lire - http://www.semanticmetadata.net/lire/) in to Solr.
Images are stored as its descriptors or features. But when searching for a image match, I need to pick images whose features are close (by calculating the distance) to the given image. Lire does this by going through all the docs in the Lucene index in a tight loop. What is the best way to implement this in Solr? Storing the feature is straight forward text or Binary field. Retrieving is a problem…. as we need to pick images below a certain distance threshold. Is this possible using a custom filter placed in the query path? ./zahoor
