Elasticsearch - What will range filter use without specifying 'execution'

Question

In the Elasticsearch documentation, it mentions that I can set an exeuction property on a range filter: https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-range-filter.html#_execution

If I don't specify the value, will it use index or fielddata by default or neither?

If you don't specify the execution mode for a range filter, it will use index by default (the value is hardcoded in the source code).

From there on, it logically follows that caching will be enabled by default as can be seen a bit further in the code.

When the documentation doesn't tell, the source code will ;)
