Hi,
I'd like to make sure that my search engine can take into account of some non-content based factors. For example, I'd like to give more score to popular docs based on # of views each document had. Another example would be to return results with search history (e.g. if we found that most ppl searched the term "school", clicked result document A, we want to boost A up when the term school appears in query) factored in.
Can someone recommend a good way of doing this?
Thanks,
Ted
