[jira] [Commented] (LUCENE-5402) Add support for index-time pruning in Document*Dictionary (Suggester)

["Michael McCandless (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LUCENE-5402?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13875613#comment-13875613 ] 

Michael McCandless commented on LUCENE-5402:
--------------------------------------------

I like the idea of being able to pass a Query to identify which documents you want to index.

But, it's spooky to pull the TopDocs with Integer.MAX_VALUE: this could suck up a lot of transient RAM.

Can we instead just pull our own Weight/Scorer/DISI and iterate the documents from that?

> It would be nice to be able to prune out entries that the suggester consumes by some query.
