Hi, I do have a question related to solr LTR plugin. I have a use case of personalization and wondering whether you can help me there. I would like to rerank my query based on the relationship of searcher with the author of the returned documents. I do have relationship score in the external datastore in form of user1(searcher), user2(author), relationship score. In my query, I can pass searcher id as external feature. My question is that during querying, how do I retrieve relationship score for each documents as a feature and rerank the documents. Would I need to implement a custom feature to do so? and How to implement the custom feature.
Thanks, Saurabh
