Hi RiH, I think the idea is interesting, but the approach you think of is a little bit difficult to implement. Imagine you got 10.000 users, than a Solr document must actually have 10.000 fields which are responsible to managing the whole stuff. Furthermore your data will change quite often. So the probability of reindexing documents would be high, since you want to update your fields on the fly to create the best user experience. So what I want to say is: the idea is good, but Solr seems to be the wrong tool to do so *alone*.
I can imagine that Solr + a database + Mahout would be a good mixture. The last one, Mahout unfortunately is not well documented at the moment (please, correct me, if I am wrong). Hope this is some usefull input for you. - Mitch -- View this message in context: http://lucene.472066.n3.nabble.com/Personalized-Search-tp831070p831245.html Sent from the Solr - User mailing list archive at Nabble.com.
