Searching by exclusions
I need to search for nodes that does not have a certain uuid value into a
multi-value property (or is empty).
I tried to do a expression like:
//element(*,nt:file)[ jcr:contains(@prop:group, '* !
9ef90c86\-734a\-414e\-84c3\-64dc6452864c') ]
in a hope to get all nodes with that property with different values that
9ef90c86\-734a\-414e\-84c3\-64dc6452864c.
In the http://lucene.apache.org/core/2_9_4/queryparsersyntax.html
...
The NOT operator excludes documents that contain the term after NOT. This is
equivalent to a difference using sets. The symbol ! can be used in place of
the word NOT.
To search for documents that contain "jakarta apache" but not "Apache
Lucene" use the query:
"jakarta apache" NOT "Apache Lucene"
Note: The NOT operator cannot be used with just one term. For example, the
following search will return no results:
NOT "jakarta apache"
...
that's why I started the terms with a "*" term, don't know the side
effects...
Any help will be appreciated,
Helio.

Justin, thanks by your post.
I did such search like you said, but it returns all nodes including the
nodes with that value in prop:group, may be because it is a multi-value
property.
Any other hint will be very appreciate, thanks!

Hi,
I think you want
//element(*,nt:file)[@prop:group != '9ef90c86-734a-414e-84c3-64dc6452864c']
You should be using the JCR specification as the point of reference. The
fact that Lucene is used is an implementation detail.
Regards,
Justin
