Index has Changed Operation

// Some index definition
const indexDefinition = new IndexDefinition();
indexDefinition.name = "UsersByName";
indexDefinition.maps = new Set([ `from user in docs.Users select new { user.Name }` ]);

// Define the has-changed operation, pass the index definition
const indexHasChangedOp = new IndexHasChangedOperation(indexDefinition);

// Execute the operation by passing it to maintenance.send
const indexHasChanged = await documentStore.maintenance.send(indexHasChangedOp);

// Return values:
// false: The definition of the index passed is the SAME as the one deployed on the server  
// true:  The definition of the index passed is DIFFERENT than the one deployed on the server
//        Or - index does not exist

const indexHasChangedOp = new IndexHasChangedOperation(definition);
