Issue With Making QueryBuilder Predicate for Tags

Hi Folks,

I had a question about building an QueryBuilder predicates in AEM java. 

I'm building a predicate that tests for more than one tag. The tag types are different, belonging to different groups in the Tag library. Here's a snippet of my code:

map.put("type", "cq:Page"); map.put("1_property", "jcr:content/cq:tags"); map.put("1_property.value",tag1); map.put("2_property","jcr:content/cq:tags"); map.put("2_property.value",tag2); map.put("3_property","jcr:content/cq:tags"); map.put("3_property.value",tag3); map.put("p.offset", "0"); map.put("p.limit", "100");

When I do this, and I tag a page, this is the behavior I'm noticing:

1. If I add tags to my page(s), and make a request for pages that contain the exact tags that I added, I get my page(s) back in the response.

2. If I add tags to my page(s), and I request for pages that have the same type/classification of tags (but not the exact same tags), I do not get a result back. This is correct behavior, and desired.

3. If I add some, but not all tags to the page, and then I make the same request for all of the tags, I still get a result back. I do not want this to happen. The request matched on some tags, but other tags were missing altogether from the page - but the page was still returned.

In other words, if a request for a tag is mismatched to the tag on a page, that page is ignored. But if a request for a tag is made and that group/class of tag is not on the page at all, the page is still returned if the query matched on the other tags. I don't want that to happen.

How can I remodel my predicate to return a page only if it has the exact tags requested, and not return a page if the requested tags are not the same OR if the requested tags are missing on the page?

If you need any clarification, please let me know, I'll be happy to oblige. Thank you.
