Using a nested object field in a multi_match query

Elastic Stack Elasticsearch
1

Hello,

I'm having trouble coming up with how to supply a field within a nested
object in the multi_match fields list. I'm using the multi_match query in
order to perform query time field boosting, but something like:

"query": {
"multi_match": {
"query": "China Mieville",
"operator": "and",
"fields": [
"_all", "title^2", "author.name^1.5"
]
}
}

doesn't seem to work. the title is boosted fine but in fact if i take out
the "_all" field then i can see that author.name is never being used. is
there a way to supply nested fields within a multi_match query?

In our case we switched the mapping type from "nested" to "object" and then
this worked. I'm aware of the implications of this switch. We don't need
the features provided by "nested". Others may, of course.

Thanks.
