Re: Combining Solr score with customized user ratings for a document

Re: Combining Solr score with customized user ratings for a document

Well, as Hoss suggested, I have implemented my own function (ValueSourceParser+ValueSource) :) It's a very simple function which receives a parameter, the userId, and returns a float value depending (with a switch-case structure just for this demo) on it. With this approach now I can boost (i.e.

Re: Combining Solr score with customized user ratings for a document

Hi Tim! Thank you for bringing in some light ;) I have read your slides (in fact, I had already read them in the last days) but I'm still missing something. So, let's see... As I see (and I may be wrong) Solr's external file fields are some kind of maps, aren't them? I understand the power of

Oops - that's definitely not the link I meant to give ;-) Here's the link from slideshare: http://www.slideshare.net/thelabdude/boosting-documents-in-solr-lucene-revolution-2011 In there we used Mahout to calculate recommendation scores and then loaded them using external file field. Cheers, Tim
