How to read all record from a model into RavenDB using C#?

Let's say we have a model as under

public class RSS
    {
        public string Id { get; set; }
        public string QuestionID { get; set; }
        public string QuestionTitle { get; set; }
        public string QuestionDescription { get; set; }
        public DateTime PublishDate { get; set; }
    }

The below piece of code will read all data from from RSS model to RavenDB

public List<RSS> ReadRssFeed(IEnumerable<string> lstIDs)
        {
            var rssCollection = new List<RSS>();
            using (var ds = new DocumentStore
            {
                Url = "http://localhost:8080",
                DefaultDatabase = "CRUDDemo"
            }.Initialize())
            using (var session = ds.OpenSession())
            {
                foreach (var id in lstIDs)
                {
                    rssCollection.Add(session.Load<RSS>(id));
                }
            }
            return rssCollection;
        }
