Hi,
I'm having trouble aggregating my nested data, maybe you can help.
I'll simplify the problem, I've a nested field that looks like:
PUT test/doc/_mapping
{
"properties": {
"fields": {
"type" : "nested",
"properties" : {
"name" : {
"type" : "keyword"
},
"value" : {
"type" : "long"
}
}
}
}
}
I created 3 documents:
PUT test/doc/1
{
"fields" : {
"name" : "aaa",
"value" : 1
}
}
PUT test/doc/2
{
"fields" : [{
"name" : "aaa",
"value" : 1
},
{
"name" : "bbb",
"value" : 2
}]
}
PUT test/doc/3
{
"fields" : [
{
"name" : "bbb",
"value" : 2
}]
}
Now I want to group my data to get how many documents there are where name="bbb" group by each value.
For the above data I want to get:
2 – 2 documents
N/A – 1 document (the first document where bbb is missing)
The problem is with the null values, I cannot find a way to match the documents where "bbb" is null and put them in a N/A bucket.
What am I missing?
Find below the first comment where I wrote a query that match the values where "bbb" exist.
But I cannot find a way to match where "bbb" not exist, in the same query.
