[jira] [Commented] (DIRSERVER-2302) Doing a search with a filter
containing (objectClass=top) fails
[ https://issues.apache.org/jira/browse/DIRSERVER-2302?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17062845#comment-17062845 ]
Emmanuel Lécharny commented on DIRSERVER-2302:
----------------------------------------------
This is a consequence of an optimization introduced a long time ago... (actually, 7 years : [https://svn.apache.org/repos/asf/directory/apacheds/trunk@1371864)]
{code:java}
for ( Value value : objectClass )
{
if ( value.equals( topOCValue ) )
{
continue;
}
String normalizedOc = objectClassNormalizer.normalize( value.getString() );
objectClassIdx.add( partitionTxn, normalizedOc, id );
}
{code}

> Key: DIRSERVER-2302
> URL: https://issues.apache.org/jira/browse/DIRSERVER-2302
> Project: Directory ApacheDS
> Issue Type: Bug
> Components: search
> Affects Versions: 2.0.0.AM26
> Reporter: Emmanuel Lécharny
> Priority: Blocker
>
> When doing a search with a filter like {{"(&(objectClass=top)(cn=blah))"}}, the search fails to return anything because the first filter element selects 0 candidate, because 'top' is not anymore indexed (there is no reason to index 'top', as every single entry has such a value).
> The problem is that the search engine does not take care of this special use case.
