Count versus Search API

Elastic Stack Elasticsearch
1

Hello,

I have a bool query with a filter applied to it, which runs against the
_search endpoint successfully giving "hits.total" but unfortunately it also
gives a lot more data than that which I don't need.

So I thought of running the same query against the _count endpoint but
there I received a
failure: "BroadcastShardOperationFailedException[[index_test][0] ]; nested:
QueryParsingException[[index_test] No query registered for [query]]; "

Is there some other lightweight manner in which I can get just "hits.total"
without the added bloat of each matching doc?

Thanks!

How does your count query look like?

I guess you are still on 0.90, where the count request is slightly
different compared to a search request, as it contains the query without it
being wrapped into the query object:

{
"term" : {"field":"value"}
}

instead of

{
"query" : {
"term" : {"field":"value"}
}
}

Beware that we changed this in 1.0 to have consistency between count api
and search api.

Hey @David, since Luca had zeroed-in-on the issue, I'll skip providing the
query this time.

@Luca - Thanks! That was exactly the problem! Another thing that is
inconsistent right now is that I can use date math against the _search
endpoint for filters but not against the _count endpoint in 0.90:
"lt" : "now",
"gte" : "now-1w"
versus:
"lt" : "2014-02-24",
"gte" : "2014-02-17"
