-This will result in an `"hasPricing"` field in the `fields` property on the `Document` object:
+Using `.addField()` ensures the field is returned with the document upon query completion:
+
+```js
+searchBuilder.addRuntimeMapping( "hasPricing", ... ).addField( "hasPricing" );
+```
+
+We can then retrieve the result field via the `getFields()` method:
 
 ```js
 var documentsWithPricing = searchBuilder.execute()
 	.getHits()
 	.filter( (document) => document.getFields()["hasPricing"] );
 ```
 
+or inlined with the document mento using `hit.getDocument( includeFields = true )`.

 ### Advanced Query DSL
 
 The SearchBuilder also allows full use of the [Elasticsearch query language](https://www.elastic.co/guide/en/elasticsearch/reference/current/_introducing_the_query_language.html), allowing full configuration of your search queries. There are several methods to provide the raw query language to the Search Builder. One is during instantiation.
