Subject [jira] Commented: (SOLR-1395) Integrate Katta
Date Mon, 11 Oct 2010 08:57:32 GMT

    [ https://issues.apache.org/jira/browse/SOLR-1395?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12919757#action_12919757
] 

Mathias Walter commented on SOLR-1395:
--------------------------------------

The two queries are not identical! In a distributed environment the first query asks each
shard for the n document Ids with the top scorces. The master merges them to the final top
n ranking documents. Then a second query to each shard is sent which requestes the solr documents
by its IDs. That's why you can see "ids=SOLR1000" in the second query.
