Is there a way to count all elements of an index in ElasticSearch or Tire?

Question

It would be nice to have a count of elements without having to do a search like

Obj.search("id:*").count

Is this possible?

Answer 1

In ElasticSearch you can count all elements using the count API

curl -XGET http://localhost:9200/index/_count

See the Count API docs on their site.

Answer 2

First, you should use the match_all query: MyModel.search( { query { all } }).results.total. (In Lucene, avoid wildcard queries at all costs.)

Presently, Tire does not expose the "count" API. That will change.
