Subject [jira] [Commented] (OAK-3371) Wrong evaluation of NOT clause
Date Mon, 21 Sep 2015 13:33:04 GMT

    [ https://issues.apache.org/jira/browse/OAK-3371?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14900693#comment-14900693

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

By looking at http://www.day.com/specs/jcr/2.0/6_Query.html#6.7.19%20FullTextSearch
I understand that a query in the format {{not contains (x, 'foo bar'}}
has to be translated into {{(not contains(x, 'foo') and not contains(x, bar))}}.

Read it as all the terms in the fulltext separated by white space must
be ANDed.

Will start working towards it.

Gave a look at your patch, but understanding the diff on top my diff
it's rather tricky. :)

> {noformat}
> SELECT * FROM [nt:unstructured] WHERE ISDESCENDANTNODE([/test]) AND NOT CONTAINS(foo,
'bar')

the property are returned as well.
