Hello Grant, Lance and Joern I have been developing 'similarity' component for OpenNLP that can be plugged into SOLR. This component does relevance assessment based on matching the parse tree of query with the parse trees of candidate answers. The idea of this component is that a search engineer does not need to be familiar with the linguistics, just plugs inSyntGenRequestHandler for longer queries or longer texts, and checks out if it improves the relevance. There are many other applications of similarity component of OpenNLP besides search which live as junits such as semantic filtering for speech recognition, content generation, and auto code generation from NL. This component is about to be released, hopefully, and is currently there: https://issues.apache.org/jira/browse/OPENNLP-497 It sounds like it is complementary to LUCENE 2899. RegardsBoris
