Hello,

I don’t find how filtering contacts using AND/OR operators. I use doctrine query parameter.  
I tested: andWhere(exprs). it didn’t worked.  
Like that:  
mauticAPI.get("/api/contacts?"+“where%5B0%5D%5Bcol%5D=”+“phone”+"&where%5B0%5D%5Bexpr%5D=isNotNull& **andWhere** %28where%5B0%5D%5Bcol%5D="+“firstname”+"&where%5B0%5D%5Bexpr%5D=like&where%5B0%5D%5Bval%5D="+"%25ac%25b%29"

NB: it works with a single expression.
