Selecting From an Array with AngularJS

How would I use a Select Option in AngularJS to select item in multiple item array. This is for a google map API application. If I select Manager1, I want to return the markers resolved to Bert Bingham etc. The examples I found is to list the items in an array[], but it doesn't return anything this way. Thanks!

JSON

var sites= [
    {name: "ABC",ISE:["Bert Bingham","Manager1"],lat:"29.9792183",lng:"-90.22268919999999"},
    {name: "Ajax",ISE:["Bert Bingham","Manager1"],lat:"30.0032515",lng:"-90.22060119999999"},
    {name: "CBS",ISE:["Bing Bingle","Manager2"],lat:"31.9703011",lng:"-90.08290799999999"},
    {name: "Turner",ISE:["Bing Bingle","Manager2"],lat:"31.004759",lng:"-90.17053299999999"},   
];
