Re: query time customized boosting
Hi, Any inputs or experience that others have come across will be really helpful to know. Basically, its the same as page ranking but the information used to decide the rank is much more dynamic in nature.. Appreciate any inputs.

I have looked at External field, query elevator and function queries but it appears that none of them Since the list of friends for a user is dynamic and per user based, it can't really be added as a field in the index for each document so I am not considering that option at all.

Re: query time customized boosting
If you have degree of separation (like friend). You could do something like: ...defType=dismaxbq=degree_of_separation:1^100 Thanks.

Re: query time customized boosting
the problem is how do I determine for each document the degree of separation and then apply boosting for example - say there is a user A - with friends X, Y, Z and another User B with friends L, M if there is a doc in index D1, with author field as Z and another doc D2 in index with author as L, It will be difficult to store degree of separation per user as an index field on the doc D1 and D2.. because for user A D1 has higher relevance but for user B its D2.. Is there a way to write our own elevation component in Solr.. On Thu, Apr 5, 2012 at 12:29 PM, William Bell billnb...@gmail.com wrote: If you have degree of separation (like friend).
