The method to apply a filter that retrieves only the array elements beginning with the letters indicated in the filter is to use the query parameter _start. For example, if you have an endpoint /users with an array of user objects, and you want to retrieve only the users whose name starts with "J", you can make a GET request to the endpoint /users?name_like=J. This will return all the users in the array whose name starts with the letter "J".
