title: Search sales orders filtered by customer using suitescript
body: <p>I need to retrieve all sales orders for a specific customer ( using customer internal id ). I can find documentation on how to perform this in SuiteTalk, but SuiteTalk's performance is abysmal and am transitioning to SuiteScript/RESTlets. </p>
  
  <p>SuiteScript v1 is available for me to use. </p>
