[jira] [Commented] (OAK-318) Excerpt support

["Thomas Mueller (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/OAK-318?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13655962#comment-13655962 ] 

Thomas Mueller commented on OAK-318:
------------------------------------

The query

{code}
/jcr:root/testroot/*[jcr:contains(., 'jackrabbit')]/rep:excerpt(.)
{code}

could be convertd to:

{code}
select 
  b.[jcr:path] as [jcr:path], 
  b.[jcr:score] as [jcr:score], 
  b.[rep:excerpt] as [rep:excerpt] 
from [nt:base] as a 
inner join [nt:base] as b on ischildnode(b, a) 
where contains(a.*, 'jackrabbit') 
and ischildnode(a, '/testroot') 
/* xpath: /jcr:root/testroot/*[jcr:contains(., 'jackrabbit')]/rep:excerpt(.) */
{code}

and then the pseudo-property "rep:excerpt" could be passed as a "not null" restriction to the filter (FilterImpl) so that the index knows that the excerpt is needed.
