Failing to query by date range using format

Elastic Stack Elasticsearch
1

Hi, trying to query records from a particular year.

"range" : {
"source.date" : {
"from" : "2014",
"to" : "2014",
"format" : "yyyy",
"include_lower" : true,
"include_upper" : true
}

Any ideas?

I can accomplish other ways, but this seems like it should work.

Never mind, found in docs.
