[jira] [Commented] (LUCENE-6326) MultiCollector does not handle CollectionTerminatedException correctly

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

    [ https://issues.apache.org/jira/browse/LUCENE-6326?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14343327#comment-14343327 ] 

Adrien Grand commented on LUCENE-6326:
--------------------------------------

+1 to make MultiCollector catch this exception. I think this is more intuitive as it would make the sub collectors collected as if they was no other collector.

> The javadoc of the *collect*-method of LeafCollector states:
> bq. Note: The collection of the current segment can be terminated by throwing a CollectionTerminatedException.
> However, the Multicollector does not catch this exception, so if one of the wrapped collectors terminates the current segment, it is terminated for every collector.
> The same is true for the *getLeafCollector*-method (even though this is not documented in the JavaDoc).
