ElasticSearch - significant term aggregation with range

I am interested to know how can I add a range for a significant terms
aggregations query. For example:

{
"query": {
"terms": {
"text_content": [
"searchTerm"
]
},
"range": {
"dateField": {
"from": "date1",
"to": "date2"
}
}
},
"aggregations": {
"significantQTypes": {
"significant_terms": {
"field": "field1",
"size": 10
}
}
},
"size": 0
}

will not work. Any suggestions on how to specify the range?
