live projections when using Advanced.LuceneQuery

[balazs]

How would one modify the example shown on
http://ravendb.net/docs/client-api/querying/static-indexes/live-projections
to use .Advanced.LuceneQuery ? That is, how would this code need to
change: documentSession.Query<Shipment, PurchaseHistoryIndex>()
.Where(x => x.UserId == userId)
.As<PurchaseHistoryViewItem>()
.ToArray();

 documentSession.Advanced.LuceneQuery< PurchaseHistoryViewItem , PurchaseHistoryIndex>()
  .Where("UserId", userId)
  .ToArray();
