[jira] [Created] (LUCENE-3555) Add support for distributed stats
Add support for distributed stats
---------------------------------
Key: LUCENE-3555
URL: https://issues.apache.org/jira/browse/LUCENE-3555
Project: Lucene - Java
Issue Type: Bug
Affects Versions: 4.0
Reporter: Robert Muir
Assignee: Robert Muir
Attachments: LUCENE-3555.patch
(its a bug in a way, since we broke this, temporarily).
There is no way to do this now (distributed IDF, etc) with the new API.
But we should do it right:
* having the sim ask the searcher for docfreq of a term is wasteful and dangerous,
usually we have already seek'd to the term and already collected the 'raw' stuff.
* the situation is more than just docfreq, because you should be able to implement
distributed scoring for all of the new sim models (or your own), that use any
of Lucene's stats.

Attached is a patch. This is also nice since it removes the "SpoofIndexSearcher" the sim tests were using to simulate fake stats.
