multi-field terms aggregation #5100
Description
It would be nice if the aggregation could be done on multiple fields to get a list of unique keys. The result should include the fields per key (where it found the term):
"example" : {
"buckets" : [ {
"key" : "java",
"doc_count" : 5
"fields": ["island", "programming language"]
}
...
]
}
