In the session we describe relevance improvements we have implemented in our Lucene-based search system for English and Chinese contents and the tests we have performed for Arabic and Spanish contents based on TREC data. We will also describe our relevance feedback web app for the end-users to rank results of various queries. The presentation will have information about the usage data we analyze to improve the relevance. We will also touch upon our OCR data indexing challenges for English and non-English content.
