[jira] Commented: (JCR-1237) Change default value for respectDocumentOrder

["Jukka Zitting (JIRA)" <ji...@apache.org>]

Jukka Zitting commented on JCR-1237:
------------------------------------

I think we should drop the QUERY_XPATH_DOC_ORDER descriptor. It's absence doesn't mean that the repository couldn't return query results in document order if so configured.

> The current default value for the search index configuration parameter respectDocumentOrder is true. Almost all applications are not interested in document order, while this default adds significant overhead to query execution because document order information is present in the index but has to be calculated over the complete result set.
> I propose to change the default value to false and document this change in the 1.4 release notes. If an application relies on document order one can still explicitly set the parameter in the configuration to true.
