I have a question related to articles. How can I search for articles with a specific label and in the same time exclude another label from them. then, we need to add a third label to all of them.
More specifically I want a to make a change on the KBs that have the label ex: 'label A' AND do not have the label ex:'label B'. When i get this list, I want to add the ex:'Label 3' label to all of them.
