The new search algorithm is still performing well and I actually use it as my default search for answering current clinical questions. But, even before this is released, I’m thinking of the next set of improvements, I have two in mind:
1) Popularity. Giving papers an additional score based on how often they have been viewed. In effect our users choices will help decide the ranking. Suggested by Dean Giustini.
2) Location. I’ve been toying with this idea for a while and saw a nice blog entry on the subject earlier today. If you’re searching from the Australia you’d probably want to see Australian guidelines before UK or Canadian guidelines. So the general idea is to see where the searcher comes from and give their countries guidelines a scoring boost.
So, the new algorithm will be released (when we go free in September) and then we can try and incorporate the above improvements sometime early 2007.
