Enable count (or other search types)

[kurtado]

Currently, we can only get the results of a query as returned in the hits array. It would be convenient to at least be able to specify just a count, or possibly other search types.

@jsvd is there a way to do this now? All i can think of is creating an aggregation so then we can access the total buckets. Which is a workaround that requires more work from an Elasticsearch standpoint.

This seems to be related to #89 as the count is just another search type.
