ResourceFilterStream.class for Content Fragment trying to .setChildSelector("[jcr:content/metadata/cq:tags]

Avatar

Level 2

Hi,

 

I am trying to filter out Content Fragment using ResourceFilterStream, but cannot do so using .setChildSelector("[jcr:content/metadata/cq:tags]

 

Doing something like below.

 

Resource resource = resourceResolver.getResource("/content/dam/test-site");
ResourceFilterStream rfs = resource.adaptTo(ResourceFilterStream.class);

rfs.setBranchSelector("[jcr:primaryType] == 'dam:Asset'")
.setChildSelector("[jcr:content/metadata/cq:tags] like 'test-site:test'")
.stream()
.forEach(r-> logger.info("found resource {}",r.getPath()));

what should be the  .setChildSelector

Hi @Aakarsh 
You should be using the JCR queries to find out the fragments. The advantages with JCR queries are you can leverage the index.

Example

 

SELECT * FROM [dam:Asset] AS cf
WHERE ISDESCENDANTNODE(cf, '/content/dam/test-site')
AND cf.[jcr:content/metadata/cq:tags] IN ('tag1', 'tag2', 'tag3')

 

Note: Please check the property name and path and adjust accordingly

Hi Arun,

 

Thank for the prompt reply, but I am familiar with JCR and SQL2 queries, wanted to use ResourceFilterStream as there are many small queries which get fired on every page load. Not using caching to wanted to use this for optimized tree traversal.

Please try with following code:

 

 ResourceFilterStream rfs = resource.adaptTo(ResourceFilterStream.class);
        rfs
                .setBranchSelector("[jcr:primaryType] != 'dam:Asset'")
                .setChildSelector("[jcr:content/metadata/cq:tags] contains $tag").addParam("tag", "properties:orientation/landscape")
                .stream()
                .forEach(r -> {
                    try {
                        resp.getWriter().println("Path: " + r.getPath());
                    } catch (IOException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }
                });

.setBranchSelector("[jcr:primaryType] != 'dam:Asset'")

this would not pick the content fragments.

.setChildSelector("[jcr:content/metadata/cq:tags] contains $tag").addParam("tag", "properties:orientation/landscape")

 is still not able to pick tags.

Hello @Aakarsh 

 

If you are adding the tags via CF properties, then the previous should work.

 

If you are adding it to a variation, via CF Edit, then its more dynamic. Please confirm, it its variation
