Hi,
I'm working with histogram aggregation but there is something strange with
keys.
For instance (cf :
http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/search-aggregations-bucket-histogram-aggregation.html):
*If I use this request :*
{
"aggs" : {
"prices" : {
"histogram" : {
"field" : "price",
"interval" : 50
}
}
}
}
*I obtain something like this :*
{
"aggregations": {
"prices" : {
"buckets": [
{
*"key_as_string" : "0",*
"key": 0,
"doc_count": 2
},
{
*"key_as_string" : "50",*
"key": 50,
"doc_count": 4
},
{
*"key_as_string" : "150",*
"key": 150,
"doc_count": 3
}
]
}
}
}
*Instead of :*
{
"aggregations": {
"prices" : {
"buckets": [
{
"key": 0,
"doc_count": 2
},
{
"key": 50,
"doc_count": 4
},
{
"key": 150,
"doc_count": 3
}
]
}
}
}
You could say, it's not important but it generates json ~1/3 bigger...
*Is there a mean to disable this ???*
Moreover, in Elasticsearch Java API, it could be fine to have a method to
request the response as a hash instead keyed by the buckets keys (cf
:http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/search-aggregations-bucket-histogram-aggregation.html#_response_format)
*Thanks!!!*
