No facets for count queries

[juniorplenty]

Using the _search endpoint with query param search_type=count allows facets to be used with count queries, and is just as performant as the _count endpoint. Currently, elastic.js doesn't provide an option to utilize this execution path.

To enable this, the doCount method should change:

var queryData = JSON.stringify(query.query);

to:

var queryData = JSON.stringify(query);

...and should set:

params.search_type="count"

(and other query types should clear that params entry)

The do* methods are for the end points. I will expose setting the search_type parameter and you can then set that to "count" and use the doSearch method to achieve what you want.

ejs.Request({indices:test})
    .searchType('count')
    .facet(whateverFacet)
    .doSearch() 

Should be pretty easy to expose the search types, I will have a look right now.

Support for search types here.
