Count operation with hasChild filter doesn't work

Elastic Stack Elasticsearch
1

Hello.

If I query from parent type using hasChild filter, there are no problems.
Everything works as expected.
But if I do a count request with the same hasChild filter, then there is a
problem:
Type [myChildType] does not have parent mapping.

There is a workaround for this: use query instead of count and use total
count returned, but this isn't optimal solution of course:)

Yes, its not supported. Use search_type=count and do a regular search, it
is as fast as the count endpoint.

Hey Shay,

Could you please explain why the count would be just as fast as a query? Is
that because count is implemented as a query and is just a convenience
operation?

Thanks
