Subject [jira] Commented: (SOLR-1632) Distributed IDF
Date Wed, 23 Feb 2011 09:27:38 GMT

    [ https://issues.apache.org/jira/browse/SOLR-1632?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12998262#comment-12998262
] 

Thorsten Scherler commented on SOLR-1632:
-----------------------------------------

Regarding the comment "Perhaps one idea is to use a visitor pattern to decouple tree traversal
with the operations being performed." can you please explain where to implement the Listener/visitor.
I had a quick look at the patch and it seems to me that the main functionality is in trunk/src/java/org/apache/solr/search/SolrIndexSearcher.java
and the rest is more caching concerns, right?

> Distributed IDF is a valuable enhancement for distributed search across non-uniform shards.
This issue tracks the proposed implementation of an API to support this functionality in Solr.
