Hi,
I am currently trying to get data using aggregation based on a nullable date field. I am using NEST API with C#. Doing this using the low-level client it was possible to get the nullable items in a separate bucket using the missing option.
"aggs":{
"top_tags":{
"date_range":{
"field" : "expiryDate",
"missing": "1899-01-01",
"ranges":[
{
"key": "MissingExpiry",
"to": "2000-01-01"
}
In the NEST API this seems to be missing. In the sense that to get the nullable values a separate aggregation has to be used. Is the feature supported or is it typical to do something else in these situations.
