Subject Re: CustomScoreQueryWithSubqueries

Robert: I'm trying to follow the steps that are mentioned in:

in order to make a patch with my contribution. But, in the source code that I 
get from:
the class is missing and the only method 
available to obtain a Scorer from a Weight object is 
scorer(IndexReader.AtomicReaderContext, ScorerContext)
I just checked and class Searcher still exists in Lucene 3.0.3. In which version 
the trunk that I've checkout is based? The patch that I want to submit is based 
on Lucene 2.9.1.
Thanks in advance.
