Yonik Seeley updated SOLR-1432:
-------------------------------

    Attachment: SOLR-1432.patch

Here's the essence of the patch that adds a simple/flexible untyped weighting scheme to ValueSource:

{code}
  /** Implementations should propagate createWeight to sub-ValueSources which can optionally store
   * weight info in the context. The context object will be passed to getValues()
   * where this info can be retrieved. */
  public void createWeight(Map context, Searcher searcher) throws IOException {
  }
{code}

> FunctionQueries aren't correctly weighted

> Nested queries in function queries aren't weighted correctly with the proper Searcher, and this is now even more serious with per-segment searching in Lucene/Solr.
