Subject [jira] Updated: (SOLR-1632) Distributed IDF
Date Tue, 08 Dec 2009 04:24:18 GMT


Andrzej Bialecki  updated SOLR-1632:

    Attachment: distrib.patch

Initial implementation. This supports the current global IDF (i.e. none ;) ), and an exact
version of global IDF that requires one additional request per query to obtain per-shard stats.

The design should be already flexible enough to implement LRU caching of docFreqs, and ultimately
to implement other methods for global IDF calculation (e.g. based on estimation or re-ranking).
