Hi,
I have a Solr collection 'products' for different products that users interact with. With MoreLikeThis, I can retrieve for a given product another related product. Now, I want to create a Solr collection for users such that I can use MoreLikeThis approach between users and products. Not just that, I would also like to get relevant product for a user based on some sort of collaborative filtering. What should be my indexing indexing and collection creation strategy to tackle this problem in general?
