Start here: https://issues.apache.org/jira/browse/LUCENE
Create an account (it's free), open an issue and set the component to "modules/grouping", fill in the fields, and submit it :) Then maybe make a patch and attach it! Genericizing the per-doc grouping key is important; we have an issue open for this already: https://issues.apache.org/jira/browse/LUCENE-3099 So in theory if we had LUCENE-3099 done, a sub-class could create a compound group key.
