You can retrieve indexed objects using the
Get method. This method requires a type (as a type parameter) and an ID and returns the indexed object of that type or null if no document is found with that ID and type.
IClient client = //A client retrieved from config or injected into the method BlogPost result = client.Get<BlogPost>(42);
One of the
Get method overloads also accept a list of IDs. Moreover, an extension method with the same name accepts a list of IDs as params. These methods return an
GetResult, which contains information about whether the document was found and, if found, the indexed object.
While indexed objects can be returned as the same type as they were before they were indexed, only the values of public properties with both a getter and a setter are populated by default.
IClient interface has another method for getting indexed objects:
GetWithMeta. This method returns the indexed object wrapped in a
GetResult object. A typical use case for this method is retrieving the object and its version number, which you can use in optimistic concurrency checks (updating objects only if they haven't changed because they are being fetched).
You might be unable to de-serialize types without parameter-less constructors or outer dependencies. In many cases, that is a sign that the types are not suitable to use as search results. In these cases, it is probably better to only fetch their IDs and then get them from the database or other backing store or project their values using the Select method. However, by adding to the
Client class conventions, you can customize how instances of a specific class are created.
