Sorry for the noob question, but is there some setting I am missing? It's
not clear to me why I'm not getting a key_as_string field in my results.
I'm running v1.1.0, here is my search:
GET /_all/_search
{
"aggs": {
"totalsByHour": {
"date_histogram": {
"field": "sessionStartTime",
"interval": "day",
"format": "yyyy-MM-dd"
}
}
}
}
and here are my results:
"aggregations": {
"totalsByHour": {
"buckets": [
{
"key": 1401667200000,
"doc_count": 15973
},
{
"key": 1401753600000,
"doc_count": 11996
},
{
"key": 1401840000000,
"doc_count": 14
},
{
"key": 1401926400000,
"doc_count": 4031
}
]
}
}
