TWsearch API Script :

var team1= tw.system.org.findTeamByName("CBE");

 for (var i = 0; i < team1.allUsers.length;i++){
                tw.local.pGroup1[i]=team1.allUsers[i].name;
               
  }
 
 
 
  var team2= tw.system.org.findTeamByName("CHE");

 for (var i = 0; i < team2.allUsers.length;i++){
                tw.local.pGroup2[i]=team2.allUsers[i].name;
               
  }

var index = 0;
 for (var i = 0; i < team1.allUsers.length;i++){
              
               var usermatch = team1.allUsers[i].name;
              
              
                for (var j = 0; j < team2.allUsers.length;j++){
                        if(usermatch == team2.allUsers[j].name){
                            tw.local.usermatch[index] = usermatch;
                            index++;
                        }
               
                 }
              
               
  }
