[jira] [Updated] (LUCENE-6537) Make NearSpansOrdered use lazy iteration

     [ https://issues.apache.org/jira/browse/LUCENE-6537?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Alan Woodward updated LUCENE-6537:
----------------------------------
    Attachment: LUCENE-6537.patch

Patch moving NearSpansOrdered to a lazy algorithm.  This makes span collection much simpler, and it will also slightly improve performance when scores are not required, as nextStartPosition() can return as soon as it finds a match, without having to shrink the spans.
