Hi all, I recently prototyped a learning to rank system in Python that produced promising results, so I'm now looking into how to replicate that process in our Solr setup. For my Python implementation, I was using a number of features that were per field text comparisons, e.g.:
1. tfidf_case_title_solution_title 2. tfidf_case_description_solution_title 3. ... 4. bm25_case_title_solution_description 5. bm25_case_description_solution_description where each solution field had its own independent index. I was wondering if any of you all had recommendations on how to do that type of thing in Solr. It looks like the SolrFeature class might be the way to go, but my colleagues who are more familiar with Solr than I am weren't sure it was possible. Thanks, Michael A. Alcorn
