[jira] [Commented] (LUCENE-4694) Add back IndexReader.fields() -> Multi*, or discourage term vectors in some better way

["Adrien Grand (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LUCENE-4694?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13556250#comment-13556250 ] 

Adrien Grand commented on LUCENE-4694:
--------------------------------------

I think there is a similar problem with doc values vs. stored fields? The API makes fetching all values of a specific field easy with stored fields and hard with doc values.

> Users can easily get term vectors from any indexreader, but not postings lists. this encourages them to do really slow things: like pulling term vectors for every single document.
> this is really really so much worse than going through multifields or whatever.
