Subject [jira] [Commented] (OAK-3371) Wrong evaluation of NOT clause
Date Tue, 08 Sep 2015 11:02:46 GMT

    [ https://issues.apache.org/jira/browse/OAK-3371?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14734622#comment-14734622

Davide Giannella commented on OAK-3371:
---------------------------------------

Quick analysis. 

Nodetype index should not play in case of full-text queries. The
full-text condition doesn't make it to the filter, nor as {{not}} nor
as {{full-text}}.

This makes the nodetype index not aware of the full-text condition and
returns all the nodes that matches the path condition.

With OAK-2050 we removed the support of Fulltext queries from the
query engine saying that full-text queries should be played only by a
full-text index (ie: lucene or solr).

Lucene should already be able to support a single {{NOT CONTAINS()}}.

So the next steps are:

- find a way to represent {{NOT CONTAINS()}} in the Filter as a
  fulltext
- Nodetype index should then not play any longer
- Ensure lucene handle correctly the condition.
- Ensure Solr handle correctly the condition.

> When executing a query like 
> {noformat}
> SELECT * FROM [nt:unstructured] WHERE ISDESCENDANTNODE([/test]) AND NOT CONTAINS(foo,
'bar')
> {noformat}
> and the {{nodeType}} index plays the not clause is not applied properly. Nodes **with**
the property are returned as well.
