XPath Question
Hi all,
I'd like to find all nodes of a certain type that have a sub node at some
level with a certain property that contains a value I'm searching for. The
following query works if I have a sub node two levels under the
nt:unstructured node:
/jcr:root//element(*, nt:unstructured)[jcr:contains(./*/*/@text, 'test')]
order by @jcr:score
But I don't know the exact level. So I tried the following:
/jcr:root//element(*, nt:unstructured)[jcr:contains(.//@text, 'test')] order
by @jcr:score
This query doesn't return any hits. But I'd expect the same result set.
Any ideas what I'm doing wrong?
Thanks
Alex

You can only have fixed relative paths inside the jcr:contains, such as
"jcr:content/foo/@text", and probably that includes wildcards. But you
can't use any Xpath axis here, i.e. not "//".

I don't know exactly, but I think if you define an index-rule, you need to
explicitly name all properties or use a wildcard matcher:
<property isRegexp="true">.*:.*</property>
But not sure if the same holds true for aggregates.

Hi,
thanks for the reply. If sub levels do not work then why is this query
working:
/jcr:root//element(*, nt:unstructured)[jcr:contains(./*/*/@text, 'test')]
order by @jcr:score
When I try index aggregates it seems that I cannot search for specific
properties anymore. At least jcr:contains(@property, 'test') is not
returning any results but jcr:contains(., 'test') does. Is this expected due
to the aggregation?
Haven't looked into joins yet but will give it a shot.
Thanks
Alex

Yes, this should work.

It does not work on sub levels.
jcr:contains(@property, 'test') is ok
jcr:contains(., 'test') is ok
jcr:contains(path/to/@property, 'test') is not ok
I've managed to make this work with a join in JQOM.
In XPath, you may look at the Index Aggregates section in IndexingConfiguration in the wiki to includes content of descendant nodes on a parent node.
