Subject E-Commerce Search: tf-idf, tie-break and boolean model
Date Mon, 16 Oct 2017 08:30:22 GMT
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.

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.

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.

Best regards,

Vincenzo D'Amore
