Solr has no mechanism for replacing the Searcher -- Solr relies on using it's own SolrIndexSearcher which is how all of that "Rest every hing should be of solr" is possible. : > Only change the searcher part.

In simpel fact: changing the Searcher won't really help you, since the Searcher isn't what computes the score anyway -- that's done by the Scorer instances that the Queyr obejcts produce -- so you could write a custom QParser that generates Query objects with Scorer's that generate your mathematical formula, or you could use a custom ValueSource (generate by a custom ValueSourceParser using hte function query syntax) to do the same calculation. -Hoss
