How can I find alfresco empty foldres using Lucene Query

问题

I want to retrieve the list of folders in a specific node whose list of childrens is empty using Lucene query.

I create this query:

+PATH:"/app:company_home/cm:contexts/cm:ctx_exploitation/cm:runs/cm:Run_322645//."+Children is empty.

but it does not give good results.

What is the right Lucene syntax to do this

回答1:

There is no way to find empty folders using a Lucene query. However, there are some java services and javascript APIs in alfresco like 'FileFolderService' in Java and 'childByNamePath' in javascript, using them you can write your logic and find empty folders.

回答2:

You can find o bytes file using below lucene query.

TYPE:"cm:content" AND @cm:content.size:0
