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..
