I am trying to figure out how to perform a complex query in elastic search, let say I have the following table of data:
Which I got from the following query
{
"aggs": {
"3": {
"terms": {
"field": "ColumnA",
"order": {
"_key": "desc"
},
"size": 50
},
"aggs": {
"4": {
"terms": {
"field": "ColumnB",
"order": {
"_key": "desc"
},
"size": 50
},
"aggs": {
"5": {
"terms": {
"field": "ColumnC",
"order": {
"_key": "desc"
},
"size": 50
},
"aggs": {
"sum_of_views": {
"sum": {
"field": "views"
}
},
"sum_of_costs": {
"sum": {
"field": "cost"
}
},
"sum_of_clicks": {
"sum": {
"field": "clicks"
}
},
"sum_of_earned": {
"sum": {
"field": "earned"
}
},
"sum_of_adv_earned": {
"sum": {
"field": "adv_earned"
}
}
}
}
}
}
}
}
},
"size": 0,
"_source": {
"excludes": []
},
"stored_fields": [
"*"
],
"script_fields": {},
"docvalue_fields": [
{
"field": "hour",
"format": "date_time"
}
],
"query": {
"bool": {
"must": [],
"filter": [
{
"match_all": {}
},
{
"range": {
"hour": {
"format": "strict_date_optional_time",
"gte": "2019-08-08T06:29:34.723Z",
"lte": "2020-08-08T06:29:34.724Z"
}
}
}
],
"should": [],
"must_not": []
}
}
}
Now for example, if I want to get the records that have the following condition
(sum_of_clicks / sum_of_views) * (sum_of_earned2 / sum_of_earned1) < 0.5
What should I query?
Think the below should help. My understanding is that you would want to first group based on ColumnA, ColumnB, ColumnC
, calculate the sum for clicks, views, earned1 and earned2
fields and then apply the custom aggregation logic you are looking for.
I've been able to come up with the below query where I've made use of Bucket Selector Aggregation .
POST <your_index_name>/_search
{
"size": 0,
"aggs": {
"3": {
"terms": {
"field": "ColumnA",
"order": {

},
"aggs": {

"terms": {
"field": "ColumnB",
"order": {
"_key": "desc"
},
"size": 50
},
"aggs": {

"terms": {
"field": "ColumnC",
"order": {
"_key": "desc"
},
"size": 50
},
"aggs": {

"sum": {
"field": "views"
}
},
"sum_clicks": {
"sum": {
"field": "clicks"
}
},
"sum_earned1": {
"sum": {
"field": "earned1"
}
},
"sum_earned2": {
"sum": {
"field": "earned2"
}
},
"custom_sum_bucket_filter": {
"bucket_selector": {
"buckets_path": {
"sum_of_views": "sum_views",
"sum_of_clicks": "sum_clicks",
"sum_of_earned1": "sum_earned1",
"sum_of_earned2": "sum_earned2"
},
"script": "(params.sum_of_views/params.sum_of_clicks) * (params.sum_of_earned1/params.sum_of_earned2) < 0.5"
}
}
}
},
"min_bucket_selector": {
"bucket_selector": {
"buckets_path": {
"valid_docs_count": "5._bucket_count"
},
"script": {
"source": "params.valid_docs_count >= 1"
}
}
}
}
},
"min_bucket_selector": {
"bucket_selector": {
"buckets_path": {
"valid_docs_count": "4._bucket_count"
},
"script": {
"source": "params.valid_docs_count >= 1"
}
}
}
}
}
}
}
Note that to get the exact result you are looking for, I've had to add the filter conditions of buckets at 4
and 5
.
The aggregations I've made use are
In order to test why I've added the additional empty bucket filters, you can just remove them and see what results you observe.
Note that for sake of simplicity I have ignored the query
part as well as the cost
field. Please feel free to add them and test it.
