Can Query Builder search on multi-value property NOT containing a value?

[EricES]

Is there a way to use Query Builder to find a multi-value property that does NOT containt a particular value?

For instance, we have a "language" property that is a multi-value String. Can Query Builder find a node where the language property does not contain 'en' (English)?

I have personally never written a query to exclude values like this. Check this for possible help -- Query Builder Predicate Reference

[EricES]

In hoping to find an undocumented predicate feature, I experimented with using multiple "operation" properties for "property". For example:

property=language

property.value=en

property.1_operation=not

property.2_operation=like

This didn't seem to work.

Hi,

Try below

property=language

property.value=en

property.operation=not

E.g.

path=/content/AEM63App/fr

type=cq:Page

property=jcr:content/language

property.value=en

property.operation=not

[EricES]

Arun - That seems to show nodes that don't have the "language" property at all. I believe that when "not" is used for "property.operation", the "property.value" predicate is ignored.

Just tested Arun;s response - this compiles --

Just tested this - it compiles and works to query We Retail pages using QueryBuilder.

             Map<String, String> map = new HashMap<String, String>();

             //set QueryBuilder search criteria                  

             map.put("type", "cq:Page");

             map.put("path", "/content/we-retail");

             map.put("property", "jcr:content/jcr:language");

             map.put("property.value", "en_CA");

             map.put("property.operation", "not");

Hi,

You got confused between 'exists' and 'not'

property.operation :

“equals” for exact match (default),

“unequals” for unequality comparison,

“like” for using the jcr:like xpath function ,

“not” for no match ,

“exists” for existence match

[smacdonald2008]

Nice response Arun!

[arunpatidar]

you can try with XPATH queries as well

/jcr:root/content/AEM63App/fr//element(*, cq:Page)

[

(not(jcr:like(jcr:content/@language, 'en')))

]

[EricES]

Arun - Your XPath example helped me understand why we were getting different results.

Though I'm working on a solution that uses Query Builder via the Java API, I tested this through the Query Builder Debugger. When I put these parameters into the Debugger:

path=/content/dam/subfolder

type=nt:unstructured

property=language

property.value=en

property.operation=not

here is the XPath that it generates:

/jcr:root/content/dam/subfolder//element(*, nt:unstructured)

[

not(@language)

]

Notice that it ignored "property.value".

However, when I add the additional "jcr:like" from your XPath example above and run the modified XPath query in the CRX Query tool:

not(jcr:like(@language, 'en'))

it works as expected. While it still returns nodes without the "language" property, it also includes nodes that have the "language" property but do not have an "en" value.

I am assuming that the Query Builder Java API behaves the same, translating to the same XPath query (or SQL2 equivalent) underneath.

We are using AEM 6.1 SP2. Is it possible that Query Builder in this version behaves differently than in newer version?

[arunpatidar]

Hi EricES​

Yes, It is not giving results as expected using QueryBuilder but with XPATH it does.

I would suggest you can go with SQL2 query instead of Query Builder.

The last XPATH query, I've shared which gives result when there is no language property or no 'en' value for language property.

If you want to check both conditions just put one more condition with AND.

/jcr:root/content/dam/subfolder//element(*, nt:unstructured)

[

@language and not(jcr:like(@language, 'en'))

]

Thanks for your help, Arun!
