(Optional, object of objects) Defines one or more [runtime fields](https://www.elastic.co/guide/en/elasticsearch/reference/current/runtime-search-request.html) in the search request. These fields take precedence over mapped fields with the same name. Properties of runtime_mappings objects <field-name> (Required, object) Configuration for the runtime field. The key is the field name. Properties of <field-name> type (Required, string) [Field type](https://www.elastic.co/guide/en/elasticsearch/reference/current/mapping-types.html), which can be any of the following: boolean composite date double geo_point ip keyword long [lookup](https://www.elastic.co/guide/en/elasticsearch/reference/current/runtime-retrieving-fields.html#lookup-runtime-fields) script (Optional, string) [Painless script](https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-scripting-using.html) executed at query time. The script has access to the entire context of a document, including the original _source and any mapped fields plus their values.`
