Hi guys
I use aggregation to collect data from nested field and stuck a little
ES allows group data by rectangle.attributes._id, but is there any way to get some 'other' bucket to put there documents that were not added to any of groups? I think bucket would be perfect because i need to do further aggregations with 'other' docs.
Or maybe there's some cool workaround?
Examples of what i have:
Documents with structure like:
{
...
rectangle: {
attributes: [
{_id: 'some_id', ...}
]
}
I use query like this for aggregation
...
"aggs": {
"attributes": {
"nested": {
"path": "rectangle.attributes"
},
"aggs": {
"attributesCount": {
"cardinality": {
"field": "rectangle.attributes._id.keyword"
}
},
"entries": {
"terms": {
"field": "rectangle.attributes._id.keyword"
}
}
}
}
}
...
And get this result
...
"buckets" : [
{
"key" : "some_parent_id",
"doc_count" : 27616,
"attributes" : {
"doc_count" : 45,
"entries" : {
"doc_count_error_upper_bound" : 0,
"sum_other_doc_count" : 0,
"buckets" : [
{
"key" : "some_id",
"doc_count" : 45,
"attributeOptionsCount" : {
"value" : 2
}
}
]
}
}
}
]
...
Is there any way to get to 'other' documents for this query? like:
...
"buckets" : [
{
"key" : "some_parent_id",
"doc_count" : 1000,
"attributes" : {
"doc_count" : 145,
"entries" : {
"doc_count_error_upper_bound" : 0,
"sum_other_doc_count" : 0,
"buckets" : [
{
"key" : "some_id",
"doc_count" : 45
},
{
"key" : "other",
"doc_count" : 100
}
]
}
}
}
]
