How do I create a Range Facet with QueryBuilder?

This may be a simple question, but I'm having trouble finding information on how to format my QueryBuilder call to add a range filter. I want my query to look like this:

{
"query" : {
    "match_all" : {}
},
"facets" : {
    "daterange" : {
        "range" : {
            "field" : "start_year",
            "ranges" : [
                { "to" : 50 },
                { "from" : 20, "to" : 70 },
                { "from" : 70, "to" : 120 },
                { "from" : 150 }
            ]
        }
    }
}
}

Here is what I have so far:

var query = new QueryBuilder<ElasticCollection>()
    .Query(q => q
        .MatchAll()
    )
    .Facets(facets => facets
        .Range(r => r.FacetName("DatabasesPerStartdate").Field("start_year").Ranges()

but I"m sort of stuck there. I can't figure out how to specify the ranges.

Also, this isn't as important, but is there a way to do multiple fields in my range facet so that it gets the count for items in "start_year" OR "end_year" ?
