I am trying to profile fields by counting documents with each given field.
I am using 1.3.0 ES, so I thought I can use:
aggs: {
docs : {
terms : {
field : _field_names,
size : 0
}
}
}
to give a count of documents with each specific field/path.
But this returns nothing for nested fields. When I use a mapping of
a : {
type : nested,
properties: {
x : {...}
y : {...}
}
}
for document structures like
a : [
{ x : ..., y: ... },
{ x : ..., y: ... }
]
The aggregate returns nothing for x and y. Is this a bug ?
Thanks,
Peter Li
