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. multiply Solr's score by a factor) the results of any query by doing something like this: http://localhost:8080/solr/Prueba/select_test?q={!boost b=rating(usuario1)}text:grapa&fl=score Where 'rating' is the name of my function. Unfortunately, I still can't see which differences are between doing this or making the product of both scores as the value for the query's sort parameter... :( Next step is, of course, replace that demo switch-case structure with a SQL query to my DB/retrieval from a Solr cache. My idea is to retrieve a <docId,recScore> map from the DB for each user that queries our system for the "first time". Next time he/she queries it I'd like to get his/her map from a Solr's cache (until info becomes obsolete). Which is the best place to do it? I think I would query the DB/cache just when the custom ValueSource is created in the ValueSourceParser's parse call, storing the map in the ValueSource. Then my floatVal method would just be a 'get' from my map. I'm so close!
