[jira] [Updated] (LUCENE-6083) Span containing/contained queries

     [ https://issues.apache.org/jira/browse/LUCENE-6083?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Paul Elschot updated LUCENE-6083:
---------------------------------
    Attachment: LUCENE-6083.patch

Patch of 3 April 2015. 
This introduces a package private class ConjunctionSpans as a common superclass for NearSpans and ContainSpans, that also does the basic work for two phase doc id iteration.

The -1 and Integer.MAX_VALUE positions have a special meaning now, so adding offsets would have added some complexity, and I avoided that for now.
