[jira] [Commented] (LUCENE-4090) PerFieldPostingsFormat cannot use name as suffix

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

    [ https://issues.apache.org/jira/browse/LUCENE-4090?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13285832#comment-13285832 ] 

Michael McCandless commented on LUCENE-4090:
--------------------------------------------

Patch looks good!  Nice having the per-field metadata...

I think it's fine to impl .equals() separately ... really getPostingsFormatPerField could work around that by holding a single instance of a given format and sharing that instance across fields.

> Currently PFPF just records the name in the metadata, which matches up to the segment suffix. But this isnt enough, e.g. someone can use Pulsing(1) on one field and Pulsing(2) on another field.
> See Mark Harwood's examples struggling with this on LUCENE-4069.
