Hi, Thanks for the reply.
I'm trying to define top hits aggregation but getting error : "Parse
Failure [Could not find aggregator type [top_hits] in [single_result]]]; }]"
This is my aggregation definition, first bucket is grouped by id and the
nested bucket is grouped by date and then I want to get only one document
from each nested bucket.
"aggs" : {
"id" : {
"terms" : {
"field" : "id"
},
"aggs" : {
"bckdate" : {
"terms" : {
"field" : "date"
},
"aggs" : {
"single_result" : {
"top_hits" : {
"sort": [
{
"id": {
"order":
"desc"
}
}
],
"_source": {
"include": [
"*"
]
},
"size" : 1
}
}
}
}
}
}
}
What could be issue with my aggregation ? I'm using ES 1.2.1
Thanks
