Hi all, I'm trying to figure out how to tune Solr for an e-commerce search.
I want to share with you what I did in the hope to understand if I was right and, if there, I could also improve my configuration. I also read that the boolean model has to be preferred in this case. https://nlp.stanford.edu/IR-book/html/htmledition/the-extended-boolean-model-versus-ranked-retrieval-1.html So, I first wrote my own implementation of DefaultSimilarity returning constantly 1.0 for TF and IDF. Now I'm struggling to understand how to configure tie-break parameter, my opinion was to configure it to 0.1 or 0.0, thats because, if I understood well, in this way the boolean model should be preferred, that's because only the maximum scoring subquery contributes to final score. https://lucene.apache.org/solr/guide/6_6/the-dismax-query-parser.html#TheDisMaxQueryParser-Thetie_TieBreaker_Parameter Not sure if this could be enough or if you need more information, thanks in advance for anyone would add a bit in this discussion.
