Hi, I'm struggling to understand how to do an UpdateRequest with the latest java client.

For example, this:

```auto
        client.update(new UpdateRequest.Builder<>()
                .index(index)
                .id(id)
                .doc(document)
                .build());

```

Won't compile, error:

```auto
Cannot resolve method 'update(co.elastic.clients.elasticsearch.core.UpdateRequest<java.lang.Object,java.lang.Object>)'

```

Can I do partial document updates using the IndexRequest instead?

An example for how to do a script in an UpdateRequest would be really great as well.

Hoping someone can point me in the right direction!

Cheers

Trying this for scripted update:

```auto
        client().update(new UpdateRequest.Builder<>()
                .index(index)
                .id(id)
                .lang("painless")
                .script(new Script.Builder()
                        .inline(new InlineScript.Builder()
                                .source("ctx._source.status = '"+ status +"'")
                                .build())
                        .build())
                .build());

```

but nothing compiles, so I don't know what's supposed to work. 🤷

Thanks for the feedback @ndtreviv. The update API requires an additional `Class` parameter.

The reason for this is the `source` parameter that allows retrieving the modified document. In your case you're not requesting it, so we can use the `Void` class.

Assuming the class of `document` is `SomeDoc`:

```java
client.update(new UpdateRequest.Builder<Void, SomeDoc>()
    .index(index)
    .id(id)
    .doc(document)
    .build(),
    Void.class // <-- additional parameter
);

```

You can also write it in a more compact form as:

```java
client.update(b -> b
    .index(index)
    .id(id)
    .doc(appData),
    Void.class
);

```

and similarly for the script update:

```java
client.update(u -> u
    .index(index)
    .id(id)
    .lang("painless")
    .script(s -> s
        .inline(i -> i
            .source("ctx._source.status = '"+ status +"'")
        )
    ),
    Void.class
);

```

Hope this helps. We're currently improving the docs, a section on the update request will be added there.
