Hi there. I need to do by code (in XML view) the same of the following image

I need to apply two rules with the AND operator (Match all of the following rules), my current code in the "context" field is: 

 
 { 'search_default_active_poa': 1, 'search_default_projects_activities': 1, } 

But I get the OR operator (Match any of the following rules). How can I solve it? Thanks in advance.
