In the example below, I ask elasticsearch for two aggregations (I've
simplified it, it's actually got some nested aggregations in there).
{
"aggregations": {
"agg1": {
"terms": {
"field": "forname"
}
},
"agg2": {
"terms": {
"field": "surname"
}
}
}
}
What I get back is two sets of results, i.e.
{
"aggregations" : {
"agg1" : {
"buckets" : [ {
"key" : "john",
"doc_count" : 1
}, {
"key" : "bob",
"doc_count" : 4
} ]
},
"agg2" : {
"buckets" : [ {
"key" : "smith",
"doc_count" : 3
}, {
"key" : "jones",
"doc_count" : 2
} ]
}
}
}
What I'd like to get back is one set of results. I.e. a list of terms
appearing in either of the fields, with the counts summed across both, e.g.
{
"aggregations" : {
"agg1 OR agg2" : {
"buckets" : [ {
"key" : "john",
"doc_count" : 1
}, {
"key" : "bob",
"doc_count" : 4
}, {
"key" : "smith",
"doc_count" : 3
}, {
"key" : "jones",
"doc_count" : 2
} ]
}
}
}
Is there any way of doing this? I could request them and merge them in my
own code, but if there's a built in way then I'd rather use that.
Thanks,
Tim.
