 Under the hood, the `withJson()` methods call the object's deserializer. The JSON text's structure and value types therefore have to be correct for the target data structure. Using `withJson()` keeps the strong typing guarantees of the {java-client}.

 ==== Creating a search request combining JSON and programmatic construction
 
 You can combine `withJson()` with regular calls to setter methods. The example below loads the query part of a search request from a `String` and programmatically adds an aggregation.

 <3> since this is an aggregation we don't care about result documents and set their target class to `Void`, meaning they will just be ignored. Note that setting `size` to zero actually prevents any document from being returned.

 ==== Creating a search request from multiple JSON snippets
 
 The `withJson()` methods are partial deserializers: the properties loaded from the JSON will set property values or replace the previous ones, but will not reset other properties not found in the JSON input. You can use this to combine multiple JSON snippets to build complex search requests (this uses `queryJson` from the previous example):
